Subject: media: cec-pin.c: use proper ktime accessor functions

Use ktime_to_ns/ns_to_ktime. This makes it possible to work with older kernels
and the media_build compatibility system.

For the mainline kernel these functions are NOPs.

Subject: media: cec-core.rst/cec-ioc-receive.rst: clarify CEC_TX_STATUS_ERROR

CEC_TX_STATUS_ERROR can be used if the HW cannot tell LOST_ARB and
LOW_DRIVE apart, or when some other error occurs. It is not a
replacement for NACK.

So the hardware must be able to tell the difference between OK, NACK and
'something else'.

Clarify the documentation (both public and kernel API) on this point.

Also fix two small typos (this messages -> this message).

Subject: media: cec: add CEC_EVENT_PIN_HPD_LOW/HIGH events

Add support for two new low-level events: PIN_HPD_LOW and PIN_HPD_HIGH.

This is specifically meant for use with the upcoming cec-gpio driver
and makes it possible to trace when the HPD pin changes. Some HDMI
sinks do strange things with the HPD and this makes it easy to debug
this.

Note that this also moves the initialization of a devnode mutex and
list to the allocate_adapter function: if the HPD is high, then as
soon as the HPD interrupt is created an interrupt occurs and
cec_queue_pin_hpd_event() is called which requires that the devnode
mutex and list are initialized.

+* HDMI CEC GPIO driver
+
+The HDMI CEC GPIO module supports CEC implementations where the CEC line
+is hooked up to a pull-up GPIO line and - optionally - the HPD line is
+hooked up to another GPIO line.
+
+Required properties:
+  - compatible: value must be "cec-gpio".
+  - cec-gpios: gpio that the CEC line is connected to. The line should be
+    tagged as open drain.
+
+If the CEC line is associated with an HDMI receiver/transmitter, then the
+following property is also required:
+
+  - hdmi-phandle - phandle to the HDMI controller, see also cec.txt.
+
+If the CEC line is not associated with an HDMI receiver/transmitter, then
+the following property is optional:
+
+  - hpd-gpios: gpio that the HPD line is connected to.
+
+Example for the Raspberry Pi 3 where the CEC line is connected to
+pin 26 aka BCM7 aka CE1 on the GPIO pin header and the HPD line is
+connected to pin 11 aka BCM17:
+
+#include <dt-bindings/gpio/gpio.h>
+
+cec-gpio {
+       compatible = "cec-gpio";
+       cec-gpios = <&gpio 7 (GPIO_ACTIVE_HIGH|GPIO_OPEN_DRAIN)>;
+       hpd-gpios = <&gpio 17 GPIO_ACTIVE_HIGH>;
+};

Subject: media: cec-gpio: add HDMI CEC GPIO driver

Add a simple HDMI CEC GPIO driver that sits on top of the cec-pin framework.

While I have heard of SoCs that use the GPIO pin for CEC (apparently an
early RockChip SoC used that), the main use-case of this driver is to
function as a debugging tool.

By connecting the CEC line to a GPIO pin on a Raspberry Pi 3 for example
it turns it into a CEC debugger and protocol analyzer.

With 'cec-ctl --monitor-pin' the CEC traffic can be analyzed.

But of course it can also be used with any hardware project where the
HDMI CEC line is hooked up to a pull-up gpio line.

In addition this has (optional) support for tracing HPD changes if the
HPD is connected to a GPIO.

Subject: media: drivers: delete unnecessary variable initialisations

The variables will be set to an appropriate value before usage.
Thus omit the explicit initialisation at the beginning.

Subject: media: drivers: improve a size determination

Replace the specification of a data structure by a pointer dereference
as the parameter for the operator "sizeof" to make the corresponding size
determination a bit safer according to the Linux coding style convention.

This issue was detected by using the Coccinelle software.

Subject: media: dvb-frontends: delete jump targets

* Return directly after a call of the function "kzalloc" failed
  at the beginning.

* Move a bit of exception handling code into an if branch.

* Delete jump targets which became unnecessary with this refactoring.

is redundant. Remove it.

Subject: media: cobalt: do not register subdev nodes

In the distant past the adv7604 driver used private controls. In order
to access them the v4l-subdevX nodes were needed. Later the is_private
tag was removed in the adv7604 driver and the need for v4l-subdevX
device nodes disappeared.

Remove the creation of those device nodes from this driver.

Note: the cobalt card is only used inside Cisco and we never actually
used the v4l-subdevX nodes for anything. So this API change can be done
safely without breaking anything.

Subject: media: fix media Kconfig help syntax issues

The help text should be indented by at least two spaces after the
'help' separator. This is both good practice and the media_build system
for building media drivers makes this assumption.

I went through all Kconfigs under drivers/media and fixed any bad help
sections. This makes it conform to the common practice and should fix
problems with 'make menuconfig' when using media_build. This is due to
a "WARNING" message that media_build can insert in the Kconfig and that
assumes the help text is indented by at least two spaces. If not, then the
Kconfig becomes invalid and 'make menuconfig' fails.

The d3_delay parameter is set by arch/x86/pci/intel_mid_pci.c and

From 8cd0cd065f3720385eef223a63dcc552ba98bc01 Mon Sep 17 00:00:00 2001
From: Nicolas Iooss
Date: Sun, 3 Sep 2017 08:05:26 -0400
Subject: media: staging/atomisp: fix header guards

Files input_formatter_subsystem_defs.h begin with:

    #ifndef _if_subsystem_defs_h
    #define _if_subsystem_defs_h__

and end with:

    #endif /* _if_subsystem_defs_h__ */

The intent seems to have been to use _if_subsystem_defs_h__ everywhere
but two underscores are missing in the initial #ifndef.

Fixes: a49d25364dfb ("staging/atomisp: Add support for the Intel IPU v2")

From: Branislav Radocaj
Date: Thu, 7 Sep 2017 12:26:42 -0400
Subject: media: Staging: atomisp: fix alloc_cast.cocci warnings

Remove casting the values returned by memory allocation functions
like kmalloc, kzalloc, kmem_cache_alloc, kmem_cache_zalloc etc.

Semantic patch information:
This makes an effort to find cases of casting of values returned by
kmalloc, kzalloc, kcalloc, kmem_cache_alloc, kmem_cache_zalloc,
kmem_cache_alloc_node, kmalloc_node and kzalloc_node and removes
the casting as it is not required. The result in the patch case may
need some reformatting.

Subject: media: Staging: media: atomisp: Use kcalloc instead of kzalloc

Use kcalloc instead of kzalloc to check for an overflow before
multiplication. Done using the following semantic patch by
coccinelle.

From: Pierre-Louis Bossart

Subject: media: staging: atomisp: use clock framework for camera clocks

The Atom ISP driver initializes and configures PMC clocks which are
already handled by the clock framework.

Remove all legacy vlv2_platform_clock stuff and move to the clk API to
avoid conflicts, e.g. with audio machine drivers enabling the MCLK for
external codecs

Fixes: a49d25364dfb ("staging/atomisp: Add support for the Intel IPU v2")

Subject: [media] media: lirc_dev: remove support for manually specifying minor
 number

All users of lirc_register_driver() uses dynamic minor allocation,
therefore we can remove the ability to explicitly request a given number.

This changes the function prototype of lirc_unregister_driver() to also
take a struct lirc_driver pointer as the sole argument.

Subject: [media] media: lirc_dev: make better use of file->private_data

By making better use of file->private_data in lirc_dev we can avoid
digging around in the irctls[] array, thereby simplifying the code.

External drivers need to use lirc_get_pdata() instead of mucking around
in file->private_data.

The newly introduced lirc_init_pdata() function isn't very elegant, but
it's a stopgap measure which can be removed once lirc_zilog is converted
to rc-core.

Subject: [media] media: lirc_dev: make chunk_size and buffer_size mandatory

Make setting chunk_size and buffer_size mandatory for drivers which
expect lirc_dev to allocate the lirc_buffer (i.e. ir-lirc-codec) and
don't set them in lirc-zilog (which creates its own buffer).

Also remove an unnecessary copy of chunk_size in struct irctl (the
same information is already available from struct lirc_buffer).

Subject: [media] media: lirc_dev: sanitize locking

Use the irctl mutex for all device operations and only use lirc_dev_lock
to protect the irctls array. Also, make sure that the device is alive
early in each fops function before doing anything else.

Since this patch touches nearly every line where the irctl mutex is
taken/released, it also renames the mutex at the same time (the name
irctl_lock will be misleading once struct irctl goes away in later
patches).

Subject: [media] media: lirc_dev: use an IDA instead of an array to keep track
 of registered devices

Using the kernel-provided IDA simplifies the code and makes it possible
to remove the lirc_dev_lock mutex.

Subject: [media] media: lirc_dev: introduce lirc_allocate_device and
 lirc_free_device

Introduce two new functions so that the API for lirc_dev matches that
of the rc-core and input subsystems.

This means that lirc_dev structs are managed using the usual four
functions:

lirc_allocate_device
lirc_free_device
lirc_register_device
lirc_unregister_device

The functions are pretty simplistic at this point, later patches will put
more flesh on the bones of both.

Subject: [media] media: lirc_zilog: add a pointer to the parent device to
 struct IR

lirc_zilog stashes a pointer to the parent device in struct lirc_dev
and uses it for logging. It makes more sense to let lirc_zilog keep
track of that pointer in its own struct (this is in preparation for
subsequent patches which will remodel struct lirc_dev).

Subject: [media] media: lirc_zilog: use a dynamically allocated lirc_dev

lirc_zilog currently embeds a struct lirc_dev in its own struct IR,
but subsequent patches will make the lifetime of struct lirc_dev
dynamic (i.e.  it will be free():d once lirc_dev is sure there are
no users of the struct).

Therefore, change lirc_zilog to use a pointer to a dynamically
allocated struct lirc_dev.

Subject: [media] media: lirc_dev: merge struct irctl into struct lirc_dev

The use of two separate structs (lirc_dev aka lirc_driver and irctl) makes
it much harder to follow the proper lifetime of the various structs and
necessitates hacks such as keeping a copy of struct lirc_dev inside
struct irctl.

Merging the two structs means that lirc_dev can properly manage the
lifetime of the resulting struct and simplifies the code at the same time.

Subject: [media] media: rc: constify usb_device_id

usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.

Subject: [media] media: rc: if protocols can't be changed, don't be writable

If the protocols of an rc device cannot be changed, ensure the sysfs
file is not writable.

This makes it possible to detect this from userspace, so ir-keytable
can deal with case without giving an error.

Subject: [media] media: imon: make two const arrays static, reduces object
 code size

Don't populate the const arrays vfd_packet6 and fp_packet on the
stack, instead make them static.  Makes the object code smaller
by over 600 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  43794	  17920	   1024	  62738	   f512	drivers/media/rc/imon.o

After:
   text	   data	    bss	    dec	    hex	filename
  42994	  18080	   1024	  62098	   f292	drivers/media/rc/imon.o

Subject: [media] media: rc: gpio-ir-recv: do not allow threaded interrupt
 handler

Requesting any context irq is not actually great idea since threaded
interrupt handler is run at too unpredictable time which turns
timing information wrong. Fix it by requesting regular interrupt.

old config should not by default get a larger kernel.

Subject: [media] gspca: make arrays static, reduces object code size

Don't populate const arrays on the stack, instead make them
static.  Makes the object code smaller by over 5200 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  58259	   8880	    128	  67267	  106c3	ov519.o

After:
   text	   data	    bss	    dec	    hex	filename
  52155	   9776	    128	  62059	   f26b	ov519.o

Subject: [media] saa7146: make saa7146_use_ops const

Make these const as they are not modified in the file referencing them.
They are only used when their function pointer fields invokes a
function and therefore none of the structure fields are getting modified.
Also, add a const to the declaration in the header.

Subject: [media] rcar_drif: fix potential uninitialized variable use

Older compilers like gcc-4.6 may run into a case that returns
an uninitialized variable from rcar_drif_enable_rx() if that
function was ever called with an empty cur_ch_mask:

drivers/media/platform/rcar_drif.c:658:2: error: ‘ret’ may be used uninitialized in this function [-Werror=uninitialized]

Newer compilers don't have that problem as they optimize the
'ret' variable away and just return zero in that case.

This changes the function to return -EINVAL for this particular
failure, to make it consistent across all compiler versions.
In case gcc gets changed to report a warning for it in the
future, it's also a good idea to shut it up now.

Subject: [media] v4l2-ctrls.c: allow empty control handlers

If you have a control handler that does not contain any controls, then
currently calling VIDIOC_G/S/TRY_EXT_CTRLS with count == 0 will return
-EINVAL in the class_check() function.

This is not correct, there is no reason why this should return an error.

The purpose of setting count to 0 is to test if the ioctl can mix controls
from different control classes. And this is possible. The fact that there
are not actually any controls defined is another matter that is unrelated
to this test.

This caused v4l2-compliance to fail, so that is fixed with this patch applied.

Subject: [media] media: ov5670: Use recommended black level and output bias

Previously, images were relatively darker due to non-optimal
settings for black target level and bias.

Now, use recommended settings for black target level and output bias
as default values. The same default settings apply to all the resolutions.
Given these recommeneded settings do not change dynamically, add these to
existing mode register settings.

Subject: [media] media: Check for active and has_no_links overrun

The active and has_no_links arrays will overrun in
media_entity_pipeline_start() if there's an entity which has more than
MEDIA_ENTITY_MAX_PAD pads. Ensure in media_entity_init() that there are
fewer pads than that.

Subject: [media] media: ov13858: Fix 4224x3136 video flickering at some
 vblanks

Previously, with crop (0, 0), (4255, 3167), VTS < 0xC9E was resulting in
blank frames sometimes. This appeared as video flickering. But we need VTS
< 0xC9E to get ~30fps.

Omni Vision recommends to use crop (0,8), (4255, 3159) for 4224x3136. With
this crop, VTS 0xC8E is supported and yields ~30fps.

Subject: [media] smiapp: Verify clock frequency after setting it, prevent
 changing it

The external clock frequency was set by the driver but the obtained
frequency was never verified. Do that.

Being able to obtain the exact frequency is important as the value is used
for PLL calculations which may result in frequencies that violate the PLL
tree limits.

Subject: [media] smiapp: Get clock rate if it's not available through DT

Obtain the clock rate from the clock framework if it's not available
through DT. The assumption is that the parent device (camera module)
defines the rate as clock control is a part of the power on and power off
sequences --- which are camera module specific.

Also use the clock rate from DT if no clock is provided.

The clock control is not explicitly controlled by the driver in two cases:
ACPI based systems and when the clock is part of the power sequence of the
camera module.

Fixes: eed008e605d1 ("[media] media: rc: gpio-ir-recv: use gpiolib API")

For some reason only partial patch was applied. Also include
gpio/consumer.h otherwise compile test fails.

There are no users of this functionality (ir-lirc-codec.c has its own
implementation and lirc_zilog.c doesn't use it) so remove it.

This only affects users of the lirc kapi, not rc-core drivers.

When receiving an nec repeat, rc_repeat() is called and then rc_keydown()
with the last decoded scancode. That last call is redundant.

Subject: media: stv6110: get rid of a srate dead code

The stv6110 has a weird code that checks if get_property
and set_property ioctls are defined. If they're, it initializes
a "srate" var from properties cache. Otherwise, it sets to
15MBaud, with won't make any sense.

Thankfully, it seems that someone else discovered the issue in
the past, as "srate" is currently not used anywhere!

So, get rid of that really weird dead code logic.

Subject: media: friio-fe: get rid of set_property()

This callback is not actually doing anything but making it to
return an error depending on the DTV frontend command. Well,
that could break userspace for no good reason, and, if needed,
should be implemented, instead, at set_frontend() callback.

So, get rid of it.

Subject: media: dvb_frontend: get rid of get_property() callback

Only lg2160 implement gets_property, but there's no need for that,
as no other driver calls this callback, as get_frontend() does the
same, and set_frontend() also calls lg2160 get_frontend().

So, get rid of it.

Subject: media: dvb_frontend: cleanup dvb_frontend_ioctl_properties()

Use a switch() on this function, just like on other ioctl
handlers and handle parameters inside each part of the
switch.

That makes it easier to integrate with the already existing
ioctl handler function.

Subject: media: dvb_frontend: cleanup ioctl handling logic

Currently, there are two handlers for ioctls:
 - dvb_frontend_ioctl_properties()
 - dvb_frontend_ioctl_legacy()

Despite their names, both handles non-legacy DVB ioctls.

Besides that, there's no reason why to not handle all ioctls
on a single handler function.

So, merge them into a single function (dvb_frontend_handle_ioctl)
and reorganize the ioctl's to indicate what's the current DVB
API and what's deprecated.

Despite the big diff, the handling logic for each ioctl is the
same as before.

Subject: media: dvb_frontend: get rid of property cache's state

In the past, I guess the idea was to use state in order to
allow an autofush logic. However, in the current code, it is
used only for debug messages, on a poor man's solution, as
there's already a debug message to indicate when the properties
got flushed.

So, just get rid of it for good.

There are too much tabs on several properties, for no good

Subject: media: dvb_frontend: fix return values for FE_SET_PROPERTY

There are several problems with regards to the return of
FE_SET_PROPERTY. The original idea were to return per-property
return codes via tvp->result field, and to return an updated
set of values.

However, that never worked. What's actually implemented is:

- the FE_SET_PROPERTY implementation doesn't call .get_frontend
  callback in order to get the actual parameters after return;

- the tvp->result field is only filled if there's no error.
  So, it is always filled with zero;

- FE_SET_PROPERTY doesn't call memdup_user() nor any other
  copy_to_user() function. So, any changes to the properties
  will be lost;

- FE_SET_PROPERTY is declared as a write-only ioctl (IOW).

While we could fix the above, it could cause regressions.

So, let's just assume what the code really does, updating
the documentation accordingly and removing the logic that
would update the discarded tvp->result.

Instead of document all kAPI into a single file, split it
on multiple ones. That makes easier to maintain each part.

As a side effect, it will produce multiple html pages, with
is a good idea.

No changes at the text. Just some chapter levels changed.

-Digital TV Frontend
-~~~~~~~~~~~~~~~~~~~
-
-The Digital TV Frontend kABI defines a driver-internal interface for

-The header file for this API is named ``dvb_frontend.h`` and located in

-
-Demodulator driver
-^^^^^^^^^^^^^^^^^^
-
-The demodulator driver is responsible to talk with the decoding part of the
-hardware. Such driver should implement :c:type:`dvb_frontend_ops`, with
-tells what type of digital TV standards are supported, and points to a
-series of functions that allow the DVB core to command the hardware via
-the code under ``drivers/media/dvb-core/dvb_frontend.c``.
-
-A typical example of such struct in a driver ``foo`` is::
-

-      supports both types, you'll need to have two separate

-The algorithm to be used is obtained via ``.get_frontend_algo``. If the driver
-doesn't fill its field at struct :c:type:`dvb_frontend_ops`, it will default to

-e. g. it will try first to use the specified center frequency ``f``,
-then, it will do ``f`` + |delta|, ``f`` - |delta|, ``f`` + 2 x |delta|,
-``f`` - 2 x |delta| and so on.
-
-If the hardware has internally a some sort of zigzag algorithm, you should
-define a ``.get_frontend_algo`` function that would return ``DVBFE_ALGO_HW``.
-
-.. note::
-
-   The core frontend support also supports

-Attaching frontend driver to the bridge driver
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
-
-Before using the Digital TV frontend core, the bridge driver should attach
-the frontend demod, tuner and SEC devices and call
-:c:func:`dvb_register_frontend()`,
-in order to register the new frontend at the subsystem. At device
-detach/removal, the bridge driver should call
-:c:func:`dvb_unregister_frontend()` to
-remove the frontend from the core and then :c:func:`dvb_frontend_detach()`
-to free the memory allocated by the frontend drivers.
-
-The drivers should also call :c:func:`dvb_frontend_suspend()` as part of
-their handler for the :c:type:`device_driver`.\ ``suspend()``, and
-:c:func:`dvb_frontend_resume()` as
-part of their handler for :c:type:`device_driver`.\ ``resume()``.
-
-A few other optional functions are provided to handle some special cases.

-
-Digital TV Frontend statistics
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Introduction
-^^^^^^^^^^^^
-
-Digital TV frontends provide a range of
-:ref:`statistics <frontend-stat-properties>` meant to help tuning the device
-and measuring the quality of service.
-
-For each statistics measurement, the driver should set the type of scale used,
-or ``FE_SCALE_NOT_AVAILABLE`` if the statistics is not available on a given
-time. Drivers should also provide the number of statistics for each type.
-that's usually 1 for most video standards [#f2]_.
-
-Drivers should initialize each statistic counters with length and
-scale at its init code. For example, if the frontend provides signal
-strength, it should have, on its init code::
-
-	struct dtv_frontend_properties *c = &state->fe.dtv_property_cache;
-
-	c->strength.len = 1;
-	c->strength.stat[0].scale = FE_SCALE_NOT_AVAILABLE;
-
-And, when the statistics got updated, set the scale::
-
-	c->strength.stat[0].scale = FE_SCALE_DECIBEL;
-	c->strength.stat[0].uvalue = strength;
-
-.. [#f2] For ISDB-T, it may provide both a global statistics and a per-layer
-   set of statistics. On such cases, len should be equal to 4. The first
-   value corresponds to the global stat; the other ones to each layer, e. g.:
-
-   - c->cnr.stat[0] for global S/N carrier ratio,
-   - c->cnr.stat[1] for Layer A S/N carrier ratio,
-   - c->cnr.stat[2] for layer B S/N carrier ratio,
-   - c->cnr.stat[3] for layer C S/N carrier ratio.
-
-.. note:: Please prefer to use ``FE_SCALE_DECIBEL`` instead of
-   ``FE_SCALE_RELATIVE`` for signal strength and CNR measurements.
-
-Groups of statistics
-^^^^^^^^^^^^^^^^^^^^
-
-There are several groups of statistics currently supported:
-
-Signal strength (:ref:`DTV-STAT-SIGNAL-STRENGTH`)
-  - Measures the signal strength level at the analog part of the tuner or
-    demod.
-
-  - Typically obtained from the gain applied to the tuner and/or frontend
-    in order to detect the carrier. When no carrier is detected, the gain is
-    at the maximum value (so, strength is on its minimal).
-
-  - As the gain is visible through the set of registers that adjust the gain,
-    typically, this statistics is always available [#f3]_.
-
-  - Drivers should try to make it available all the times, as this statistics
-    can be used when adjusting an antenna position and to check for troubles
-    at the cabling.
-
-  .. [#f3] On a few devices, the gain keeps floating if no carrier.
-     On such devices, strength report should check first if carrier is
-     detected at the tuner (``FE_HAS_CARRIER``, see :c:type:`fe_status`),
-     and otherwise return the lowest possible value.
-
-Carrier Signal to Noise ratio (:ref:`DTV-STAT-CNR`)
-  - Signal to Noise ratio for the main carrier.
-
-  - Signal to Noise measurement depends on the device. On some hardware, is
-    available when the main carrier is detected. On those hardware, CNR
-    measurement usually comes from the tuner (e. g. after ``FE_HAS_CARRIER``,
-    see :c:type:`fe_status`).
-
-    On other devices, it requires inner FEC decoding,
-    as the frontend measures it indirectly from other parameters (e. g. after
-    ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
-
-    Having it available after inner FEC is more common.
-
-Bit counts post-FEC (:ref:`DTV-STAT-POST-ERROR-BIT-COUNT` and :ref:`DTV-STAT-POST-TOTAL-BIT-COUNT`)
-  - Those counters measure the number of bits and bit errors errors after
-    the forward error correction (FEC) on the inner coding block
-    (after Viterbi, LDPC or other inner code).
-
-  - Due to its nature, those statistics depend on full coding lock
-    (e. g. after ``FE_HAS_SYNC`` or after ``FE_HAS_LOCK``,
-    see :c:type:`fe_status`).
-
-Bit counts pre-FEC (:ref:`DTV-STAT-PRE-ERROR-BIT-COUNT` and :ref:`DTV-STAT-PRE-TOTAL-BIT-COUNT`)
-  - Those counters measure the number of bits and bit errors errors before
-    the forward error correction (FEC) on the inner coding block
-    (before Viterbi, LDPC or other inner code).
-
-  - Not all frontends provide this kind of statistics.
-
-  - Due to its nature, those statistics depend on inner coding lock (e. g.
-    after ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
-
-Block counts (:ref:`DTV-STAT-ERROR-BLOCK-COUNT` and :ref:`DTV-STAT-TOTAL-BLOCK-COUNT`)
-  - Those counters measure the number of blocks and block errors errors after
-    the forward error correction (FEC) on the inner coding block
-    (before Viterbi, LDPC or other inner code).
-
-  - Due to its nature, those statistics depend on full coding lock
-    (e. g. after ``FE_HAS_SYNC`` or after
-    ``FE_HAS_LOCK``, see :c:type:`fe_status`).
-
-.. note:: All counters should be monotonically increased as they're
-   collected from the hardware.
-
-A typical example of the logic that handle status and statistics is::
-
-	static int foo_get_status_and_stats(struct dvb_frontend *fe)
-	{
-		struct foo_state *state = fe->demodulator_priv;
-		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
-
-		int rc;
-		enum fe_status *status;
-
-		/* Both status and strength are always available */
-		rc = foo_read_status(fe, &status);
-		if (rc < 0)
-			return rc;
-
-		rc = foo_read_strength(fe);
-		if (rc < 0)
-			return rc;
-
-		/* Check if CNR is available */
-		if (!(fe->status & FE_HAS_CARRIER))
-			return 0;
-
-		rc = foo_read_cnr(fe);
-		if (rc < 0)
-			return rc;
-
-		/* Check if pre-BER stats are available */
-		if (!(fe->status & FE_HAS_VITERBI))
-			return 0;
-
-		rc = foo_get_pre_ber(fe);
-		if (rc < 0)
-			return rc;
-
-		/* Check if post-BER stats are available */
-		if (!(fe->status & FE_HAS_SYNC))
-			return 0;
-
-		rc = foo_get_post_ber(fe);
-		if (rc < 0)
-			return rc;
-	}
-
-	static const struct dvb_frontend_ops ops = {
-		/* ... */
-		.read_status = foo_get_status_and_stats,
-	};
-
-Statistics collect
-^^^^^^^^^^^^^^^^^^
-
-On almost all frontend hardware, the bit and byte counts are stored by
-the hardware after a certain amount of time or after the total bit/block
-counter reaches a certain value (usually programable), for example, on
-every 1000 ms or after receiving 1,000,000 bits.
-
-So, if you read the registers too soon, you'll end by reading the same
-value as in the previous reading, causing the monotonic value to be
-incremented too often.
-
-Drivers should take the responsibility to avoid too often reads. That
-can be done using two approaches:
-
-if the driver have a bit that indicates when a collected data is ready
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-
-Driver should check such bit before making the statistics available.
-
-An example of such behavior can be found at this code snippet (adapted
-from mb86a20s driver's logic)::
-
-	static int foo_get_pre_ber(struct dvb_frontend *fe)
-	{
-		struct foo_state *state = fe->demodulator_priv;
-		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
-		int rc, bit_error;
-
-		/* Check if the BER measures are already available */
-		rc = foo_read_u8(state, 0x54);
-		if (rc < 0)
-			return rc;
-
-		if (!rc)
-			return 0;
-
-		/* Read Bit Error Count */
-		bit_error = foo_read_u32(state, 0x55);
-		if (bit_error < 0)
-			return bit_error;
-
-		/* Read Total Bit Count */
-		rc = foo_read_u32(state, 0x51);
-		if (rc < 0)
-			return rc;
-
-		c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
-		c->pre_bit_error.stat[0].uvalue += bit_error;
-		c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
-		c->pre_bit_count.stat[0].uvalue += rc;
-
-		return 0;
-	}
-
-If the driver doesn't provide a statistics available check bit
-%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
-
-A few devices, however, may not provide a way to check if the stats are
-available (or the way to check it is unknown). They may not even provide
-a way to directly read the total number of bits or blocks.
-
-On those devices, the driver need to ensure that it won't be reading from
-the register too often and/or estimate the total number of bits/blocks.
-
-On such drivers, a typical routine to get statistics would be like
-(adapted from dib8000 driver's logic)::
-
-	struct foo_state {
-		/* ... */
-
-		unsigned long per_jiffies_stats;
-	}
-
-	static int foo_get_pre_ber(struct dvb_frontend *fe)
-	{
-		struct foo_state *state = fe->demodulator_priv;
-		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
-		int rc, bit_error;
-		u64 bits;
-
-		/* Check if time for stats was elapsed */
-		if (!time_after(jiffies, state->per_jiffies_stats))
-			return 0;
-
-		/* Next stat should be collected in 1000 ms */
-		state->per_jiffies_stats = jiffies + msecs_to_jiffies(1000);
-
-		/* Read Bit Error Count */
-		bit_error = foo_read_u32(state, 0x55);
-		if (bit_error < 0)
-			return bit_error;
-
-		/*
-		 * On this particular frontend, there's no register that
-		 * would provide the number of bits per 1000ms sample. So,
-		 * some function would calculate it based on DTV properties
-		 */
-		bits = get_number_of_bits_per_1000ms(fe);
-
-		c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
-		c->pre_bit_error.stat[0].uvalue += bit_error;
-		c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
-		c->pre_bit_count.stat[0].uvalue += bits;
-
-		return 0;
-	}
-
-Please notice that, on both cases, we're getting the statistics using the
-:c:type:`dvb_frontend_ops` ``.read_status`` callback. The rationale is that
-the frontend core will automatically call this function periodically
-(usually, 3 times per second, when the frontend is locked).
-
-That warrants that we won't miss to collect a counter and increment the
-monotonic stats at the right time.

+Digital TV Demux kABI
+---------------------
+
+Digital TV Demux
+~~~~~~~~~~~~~~~~
+
+The Kernel Digital TV Demux kABI defines a driver-internal interface for
+registering low-level, hardware specific driver to a hardware independent
+demux layer. It is only of interest for Digital TV device driver writers.
+The header file for this kABI is named demux.h and located in
+drivers/media/dvb-core.
+
+The demux kABI should be implemented for each demux in the system. It is
+used to select the TS source of a demux and to manage the demux resources.
+When the demux client allocates a resource via the demux kABI, it receives
+a pointer to the kABI of that resource.
+
+Each demux receives its TS input from a DVB front-end or from memory, as
+set via this demux kABI. In a system with more than one front-end, the kABI
+can be used to select one of the DVB front-ends as a TS source for a demux,

+
+The demux kABI only controls front-ends regarding to their connections with
+demuxes; the kABI used to set the other front-end parameters, such as

+Digital TV Frontend kABI
+------------------------
+
+Digital TV Frontend
+~~~~~~~~~~~~~~~~~~~
+
+The Digital TV Frontend kABI defines a driver-internal interface for
+registering low-level, hardware specific driver to a hardware independent
+frontend layer. It is only of interest for Digital TV device driver writers.
+The header file for this API is named ``dvb_frontend.h`` and located in
+``drivers/media/dvb-core``.
+
+Demodulator driver
+^^^^^^^^^^^^^^^^^^
+
+The demodulator driver is responsible to talk with the decoding part of the
+hardware. Such driver should implement :c:type:`dvb_frontend_ops`, with
+tells what type of digital TV standards are supported, and points to a
+series of functions that allow the DVB core to command the hardware via
+the code under ``drivers/media/dvb-core/dvb_frontend.c``.
+
+A typical example of such struct in a driver ``foo`` is::
+
+	static struct dvb_frontend_ops foo_ops = {
+		.delsys = { SYS_DVBT, SYS_DVBT2, SYS_DVBC_ANNEX_A },
+		.info = {
+			.name	= "foo DVB-T/T2/C driver",
+			.caps = FE_CAN_FEC_1_2 |
+				FE_CAN_FEC_2_3 |
+				FE_CAN_FEC_3_4 |
+				FE_CAN_FEC_5_6 |
+				FE_CAN_FEC_7_8 |
+				FE_CAN_FEC_AUTO |
+				FE_CAN_QPSK |
+				FE_CAN_QAM_16 |
+				FE_CAN_QAM_32 |
+				FE_CAN_QAM_64 |
+				FE_CAN_QAM_128 |
+				FE_CAN_QAM_256 |
+				FE_CAN_QAM_AUTO |
+				FE_CAN_TRANSMISSION_MODE_AUTO |
+				FE_CAN_GUARD_INTERVAL_AUTO |
+				FE_CAN_HIERARCHY_AUTO |
+				FE_CAN_MUTE_TS |
+				FE_CAN_2G_MODULATION,
+			.frequency_min = 42000000, /* Hz */
+			.frequency_max = 1002000000, /* Hz */
+			.symbol_rate_min = 870000,
+			.symbol_rate_max = 11700000
+		},
+		.init = foo_init,
+		.sleep = foo_sleep,
+		.release = foo_release,
+		.set_frontend = foo_set_frontend,
+		.get_frontend = foo_get_frontend,
+		.read_status = foo_get_status_and_stats,
+		.tune = foo_tune,
+		.i2c_gate_ctrl = foo_i2c_gate_ctrl,
+		.get_frontend_algo = foo_get_algo,
+	};
+
+A typical example of such struct in a driver ``bar`` meant to be used on
+Satellite TV reception is::
+
+	static const struct dvb_frontend_ops bar_ops = {
+		.delsys = { SYS_DVBS, SYS_DVBS2 },
+		.info = {
+			.name		= "Bar DVB-S/S2 demodulator",
+			.frequency_min	= 500000, /* KHz */
+			.frequency_max	= 2500000, /* KHz */
+			.frequency_stepsize	= 0,
+			.symbol_rate_min = 1000000,
+			.symbol_rate_max = 45000000,
+			.symbol_rate_tolerance = 500,
+			.caps = FE_CAN_INVERSION_AUTO |
+				FE_CAN_FEC_AUTO |
+				FE_CAN_QPSK,
+		},
+		.init = bar_init,
+		.sleep = bar_sleep,
+		.release = bar_release,
+		.set_frontend = bar_set_frontend,
+		.get_frontend = bar_get_frontend,
+		.read_status = bar_get_status_and_stats,
+		.i2c_gate_ctrl = bar_i2c_gate_ctrl,
+		.get_frontend_algo = bar_get_algo,
+		.tune = bar_tune,
+
+		/* Satellite-specific */
+		.diseqc_send_master_cmd = bar_send_diseqc_msg,
+		.diseqc_send_burst = bar_send_burst,
+		.set_tone = bar_set_tone,
+		.set_voltage = bar_set_voltage,
+	};
+
+.. note::
+
+   #) For satellite digital TV standards (DVB-S, DVB-S2, ISDB-S), the
+      frequencies are specified in kHz, while, for terrestrial and cable
+      standards, they're specified in Hz. Due to that, if the same frontend
+      supports both types, you'll need to have two separate
+      :c:type:`dvb_frontend_ops` structures, one for each standard.
+   #) The ``.i2c_gate_ctrl`` field is present only when the hardware has
+      allows controlling an I2C gate (either directly of via some GPIO pin),
+      in order to remove the tuner from the I2C bus after a channel is
+      tuned.
+   #) All new drivers should implement the
+      :ref:`DVBv5 statistics <dvbv5_stats>` via ``.read_status``.
+      Yet, there are a number of callbacks meant to get statistics for
+      signal strength, S/N and UCB. Those are there to provide backward
+      compatibility with legacy applications that don't support the DVBv5
+      API. Implementing those callbacks are optional. Those callbacks may be
+      removed in the future, after we have all existing drivers supporting
+      DVBv5 stats.
+   #) Other callbacks are required for satellite TV standards, in order to
+      control LNBf and DiSEqC: ``.diseqc_send_master_cmd``,
+      ``.diseqc_send_burst``, ``.set_tone``, ``.set_voltage``.
+
+.. |delta|   unicode:: U+00394
+
+The ``drivers/media/dvb-core/dvb_frontend.c`` has a kernel thread with is
+responsible for tuning the device. It supports multiple algoritms to
+detect a channel, as defined at enum :c:func:`dvbfe_algo`.
+
+The algorithm to be used is obtained via ``.get_frontend_algo``. If the driver
+doesn't fill its field at struct :c:type:`dvb_frontend_ops`, it will default to
+``DVBFE_ALGO_SW``, meaning that the dvb-core will do a zigzag when tuning,
+e. g. it will try first to use the specified center frequency ``f``,
+then, it will do ``f`` + |delta|, ``f`` - |delta|, ``f`` + 2 x |delta|,
+``f`` - 2 x |delta| and so on.
+
+If the hardware has internally a some sort of zigzag algorithm, you should
+define a ``.get_frontend_algo`` function that would return ``DVBFE_ALGO_HW``.
+
+.. note::
+
+   The core frontend support also supports
+   a third type (``DVBFE_ALGO_CUSTOM``), in order to allow the driver to
+   define its own hardware-assisted algorithm. Very few hardware need to
+   use it nowadays. Using ``DVBFE_ALGO_CUSTOM`` require to provide other
+   function callbacks at struct :c:type:`dvb_frontend_ops`.
+
+Attaching frontend driver to the bridge driver
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Before using the Digital TV frontend core, the bridge driver should attach
+the frontend demod, tuner and SEC devices and call
+:c:func:`dvb_register_frontend()`,
+in order to register the new frontend at the subsystem. At device
+detach/removal, the bridge driver should call
+:c:func:`dvb_unregister_frontend()` to
+remove the frontend from the core and then :c:func:`dvb_frontend_detach()`
+to free the memory allocated by the frontend drivers.
+
+The drivers should also call :c:func:`dvb_frontend_suspend()` as part of
+their handler for the :c:type:`device_driver`.\ ``suspend()``, and
+:c:func:`dvb_frontend_resume()` as
+part of their handler for :c:type:`device_driver`.\ ``resume()``.
+
+A few other optional functions are provided to handle some special cases.

+
+Digital TV Frontend statistics
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Introduction
+^^^^^^^^^^^^
+
+Digital TV frontends provide a range of
+:ref:`statistics <frontend-stat-properties>` meant to help tuning the device
+and measuring the quality of service.
+
+For each statistics measurement, the driver should set the type of scale used,
+or ``FE_SCALE_NOT_AVAILABLE`` if the statistics is not available on a given
+time. Drivers should also provide the number of statistics for each type.
+that's usually 1 for most video standards [#f2]_.
+
+Drivers should initialize each statistic counters with length and
+scale at its init code. For example, if the frontend provides signal
+strength, it should have, on its init code::
+
+	struct dtv_frontend_properties *c = &state->fe.dtv_property_cache;
+
+	c->strength.len = 1;
+	c->strength.stat[0].scale = FE_SCALE_NOT_AVAILABLE;
+
+And, when the statistics got updated, set the scale::
+
+	c->strength.stat[0].scale = FE_SCALE_DECIBEL;
+	c->strength.stat[0].uvalue = strength;
+
+.. [#f2] For ISDB-T, it may provide both a global statistics and a per-layer
+   set of statistics. On such cases, len should be equal to 4. The first
+   value corresponds to the global stat; the other ones to each layer, e. g.:
+
+   - c->cnr.stat[0] for global S/N carrier ratio,
+   - c->cnr.stat[1] for Layer A S/N carrier ratio,
+   - c->cnr.stat[2] for layer B S/N carrier ratio,
+   - c->cnr.stat[3] for layer C S/N carrier ratio.
+
+.. note:: Please prefer to use ``FE_SCALE_DECIBEL`` instead of
+   ``FE_SCALE_RELATIVE`` for signal strength and CNR measurements.
+
+Groups of statistics
+^^^^^^^^^^^^^^^^^^^^
+
+There are several groups of statistics currently supported:
+
+Signal strength (:ref:`DTV-STAT-SIGNAL-STRENGTH`)
+  - Measures the signal strength level at the analog part of the tuner or
+    demod.
+
+  - Typically obtained from the gain applied to the tuner and/or frontend
+    in order to detect the carrier. When no carrier is detected, the gain is
+    at the maximum value (so, strength is on its minimal).
+
+  - As the gain is visible through the set of registers that adjust the gain,
+    typically, this statistics is always available [#f3]_.
+
+  - Drivers should try to make it available all the times, as this statistics
+    can be used when adjusting an antenna position and to check for troubles
+    at the cabling.
+
+  .. [#f3] On a few devices, the gain keeps floating if no carrier.
+     On such devices, strength report should check first if carrier is
+     detected at the tuner (``FE_HAS_CARRIER``, see :c:type:`fe_status`),
+     and otherwise return the lowest possible value.
+
+Carrier Signal to Noise ratio (:ref:`DTV-STAT-CNR`)
+  - Signal to Noise ratio for the main carrier.
+
+  - Signal to Noise measurement depends on the device. On some hardware, is
+    available when the main carrier is detected. On those hardware, CNR
+    measurement usually comes from the tuner (e. g. after ``FE_HAS_CARRIER``,
+    see :c:type:`fe_status`).
+
+    On other devices, it requires inner FEC decoding,
+    as the frontend measures it indirectly from other parameters (e. g. after
+    ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+    Having it available after inner FEC is more common.
+
+Bit counts post-FEC (:ref:`DTV-STAT-POST-ERROR-BIT-COUNT` and :ref:`DTV-STAT-POST-TOTAL-BIT-COUNT`)
+  - Those counters measure the number of bits and bit errors errors after
+    the forward error correction (FEC) on the inner coding block
+    (after Viterbi, LDPC or other inner code).
+
+  - Due to its nature, those statistics depend on full coding lock
+    (e. g. after ``FE_HAS_SYNC`` or after ``FE_HAS_LOCK``,
+    see :c:type:`fe_status`).
+
+Bit counts pre-FEC (:ref:`DTV-STAT-PRE-ERROR-BIT-COUNT` and :ref:`DTV-STAT-PRE-TOTAL-BIT-COUNT`)
+  - Those counters measure the number of bits and bit errors errors before
+    the forward error correction (FEC) on the inner coding block
+    (before Viterbi, LDPC or other inner code).
+
+  - Not all frontends provide this kind of statistics.
+
+  - Due to its nature, those statistics depend on inner coding lock (e. g.
+    after ``FE_HAS_VITERBI``, see :c:type:`fe_status`).
+
+Block counts (:ref:`DTV-STAT-ERROR-BLOCK-COUNT` and :ref:`DTV-STAT-TOTAL-BLOCK-COUNT`)
+  - Those counters measure the number of blocks and block errors errors after
+    the forward error correction (FEC) on the inner coding block
+    (before Viterbi, LDPC or other inner code).
+
+  - Due to its nature, those statistics depend on full coding lock
+    (e. g. after ``FE_HAS_SYNC`` or after
+    ``FE_HAS_LOCK``, see :c:type:`fe_status`).
+
+.. note:: All counters should be monotonically increased as they're
+   collected from the hardware.
+
+A typical example of the logic that handle status and statistics is::
+
+	static int foo_get_status_and_stats(struct dvb_frontend *fe)
+	{
+		struct foo_state *state = fe->demodulator_priv;
+		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+
+		int rc;
+		enum fe_status *status;
+
+		/* Both status and strength are always available */
+		rc = foo_read_status(fe, &status);
+		if (rc < 0)
+			return rc;
+
+		rc = foo_read_strength(fe);
+		if (rc < 0)
+			return rc;
+
+		/* Check if CNR is available */
+		if (!(fe->status & FE_HAS_CARRIER))
+			return 0;
+
+		rc = foo_read_cnr(fe);
+		if (rc < 0)
+			return rc;
+
+		/* Check if pre-BER stats are available */
+		if (!(fe->status & FE_HAS_VITERBI))
+			return 0;
+
+		rc = foo_get_pre_ber(fe);
+		if (rc < 0)
+			return rc;
+
+		/* Check if post-BER stats are available */
+		if (!(fe->status & FE_HAS_SYNC))
+			return 0;
+
+		rc = foo_get_post_ber(fe);
+		if (rc < 0)
+			return rc;
+	}
+
+	static const struct dvb_frontend_ops ops = {
+		/* ... */
+		.read_status = foo_get_status_and_stats,
+	};
+
+Statistics collect
+^^^^^^^^^^^^^^^^^^
+
+On almost all frontend hardware, the bit and byte counts are stored by
+the hardware after a certain amount of time or after the total bit/block
+counter reaches a certain value (usually programable), for example, on
+every 1000 ms or after receiving 1,000,000 bits.
+
+So, if you read the registers too soon, you'll end by reading the same
+value as in the previous reading, causing the monotonic value to be
+incremented too often.
+
+Drivers should take the responsibility to avoid too often reads. That
+can be done using two approaches:
+
+if the driver have a bit that indicates when a collected data is ready
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+Driver should check such bit before making the statistics available.
+
+An example of such behavior can be found at this code snippet (adapted
+from mb86a20s driver's logic)::
+
+	static int foo_get_pre_ber(struct dvb_frontend *fe)
+	{
+		struct foo_state *state = fe->demodulator_priv;
+		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+		int rc, bit_error;
+
+		/* Check if the BER measures are already available */
+		rc = foo_read_u8(state, 0x54);
+		if (rc < 0)
+			return rc;
+
+		if (!rc)
+			return 0;
+
+		/* Read Bit Error Count */
+		bit_error = foo_read_u32(state, 0x55);
+		if (bit_error < 0)
+			return bit_error;
+
+		/* Read Total Bit Count */
+		rc = foo_read_u32(state, 0x51);
+		if (rc < 0)
+			return rc;
+
+		c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+		c->pre_bit_error.stat[0].uvalue += bit_error;
+		c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+		c->pre_bit_count.stat[0].uvalue += rc;
+
+		return 0;
+	}
+
+If the driver doesn't provide a statistics available check bit
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+
+A few devices, however, may not provide a way to check if the stats are
+available (or the way to check it is unknown). They may not even provide
+a way to directly read the total number of bits or blocks.
+
+On those devices, the driver need to ensure that it won't be reading from
+the register too often and/or estimate the total number of bits/blocks.
+
+On such drivers, a typical routine to get statistics would be like
+(adapted from dib8000 driver's logic)::
+
+	struct foo_state {
+		/* ... */
+
+		unsigned long per_jiffies_stats;
+	}
+
+	static int foo_get_pre_ber(struct dvb_frontend *fe)
+	{
+		struct foo_state *state = fe->demodulator_priv;
+		struct dtv_frontend_properties *c = &fe->dtv_property_cache;
+		int rc, bit_error;
+		u64 bits;
+
+		/* Check if time for stats was elapsed */
+		if (!time_after(jiffies, state->per_jiffies_stats))
+			return 0;
+
+		/* Next stat should be collected in 1000 ms */
+		state->per_jiffies_stats = jiffies + msecs_to_jiffies(1000);
+
+		/* Read Bit Error Count */
+		bit_error = foo_read_u32(state, 0x55);
+		if (bit_error < 0)
+			return bit_error;
+
+		/*
+		 * On this particular frontend, there's no register that
+		 * would provide the number of bits per 1000ms sample. So,
+		 * some function would calculate it based on DTV properties
+		 */
+		bits = get_number_of_bits_per_1000ms(fe);
+
+		c->pre_bit_error.stat[0].scale = FE_SCALE_COUNTER;
+		c->pre_bit_error.stat[0].uvalue += bit_error;
+		c->pre_bit_count.stat[0].scale = FE_SCALE_COUNTER;
+		c->pre_bit_count.stat[0].uvalue += bits;
+
+		return 0;
+	}
+
+Please notice that, on both cases, we're getting the statistics using the
+:c:type:`dvb_frontend_ops` ``.read_status`` callback. The rationale is that
+the frontend core will automatically call this function periodically
+(usually, 3 times per second, when the frontend is locked).
+
+That warrants that we won't miss to collect a counter and increment the
+monotonic stats at the right time.

Subject: media: dvb_frontend: dtv_property_process_set() cleanups

Since all properties in the func dtv_property_process_set() use
at most 4 bytes arguments, change the code to pass
u32 cmd and u32 data as function arguments, instead of passing a
pointer to the entire struct dtv_property *tvp.

Instead of having a generic dtv_property_dump(), added its own
properties debug logic in the dtv_property_process_set().

The functions used on dvb_demux.h are largely used on DVB drivers.
Yet, none of them are documented.

No functional changes.

Subject: media: dvb uAPI docs: get rid of examples section

That section is too outdated and got superseded by DVBv5 and
by libdvbv5.

Maybe some day we'll end adding updated examples there, but
while nobody has time or interest of doing that, just mention
that there and get rid of the current examples for good.

Subject: Simplify major/minor non-dynamic logic

changeset 6bbf7a855d20 ("media: dvbdev: convert DVB device types into an enum")
added a new warning on gcc 6:

>> drivers/media/dvb-core/dvbdev.c:86:1: warning: control reaches end of non-void function [-Wreturn-type]

That's because gcc is not smart enough to see that all types are
present at the switch. Also, the current code is not too optimized.

So, replace it to a more optimized one, based on a static table.

Subject: [media] rockchip/rga: v4l2 m2m support

Rockchip RGA is a separate 2D raster graphic acceleration unit. It
accelerates 2D graphics operations, such as point/line drawing, image
scaling, rotation, BitBLT, alpha blending and image blur/sharpness

The driver supports various operations from the rendering pipeline.
 - copy
 - fast solid color fill
 - rotation
 - flip
 - alpha blending

The code in rga-hw.c is used to configure regs according to operations
The code in rga-buf.c is used to create private mmu table for RGA.

Exynos 5250 and 5420 have different hardware rotation limits.
Since we have to distinguish between these two, we add different
compatible: samsung,exynos5250-gsc and samsung,exynos5420-gsc.

Subject: media: smiapp: Rely on runtime PM

Instead of relying on a mix of runtime PM and the s_power() callback, drop
the s_power() callback altogether and use runtime PM solely.

As device access is required during device power-on and power-off
sequences, runtime PM alone cannot tell whether the device is available.
Thus the "active" field is introduced in struct smiapp_sensor to tell
whether it is safe to write to the device.

Consequently there is no need to power on the device whenever a file
handle is open. This functionality is removed as well. The user may still
control the device power management through sysfs. Autosuspend remains
enabled, with 1 s delay.

Subject: media: atmel-isc: Add prepare and unprepare ops

A software write operation to the ISC_CLKEN or ISC_CLKDIS register
requires double clock domain synchronization and is not permitted
when the ISC_SR.SIP is asserted. So add the .prepare and .unprepare
ops to make sure the ISC_CLKSR.SIP is unasserted before the write
operation to the ISC_CLKEN or ISC_CLKDIS register.

To meet the relationship, enable the HCLOCK and ispck during the
device probe, "isc_pck frequency is less than or equal to isc_ispck,
and isc_ispck is greater than or equal to HCLOCK."
Meanwhile, call the pm_runtime_enable() in the right place.

Subject: media: atmel-isc: Rework the format list

To improve the readability of code, split the format array into two,
one for the format description, other for the register configuration.
Meanwhile, add the flag member to indicate the format can be achieved
from the sensor or be produced by the controller, and rename members
related to the register configuration.

Also add more formats support: GREY, ARGB444, ARGB555 and ARGB32.

Subject: media: venus: reimplement decoder stop command

This addresses the wrong behavior of decoder stop command by
rewriting it. These new implementation enqueue an empty buffer
on the decoder input buffer queue to signal end-of-stream. The
client should stop queuing buffers on the V4L2 Output queue
and continue queuing/dequeuing buffers on Capture queue. This
process will continue until the client receives a buffer with
V4L2_BUF_FLAG_LAST flag raised, which means that this is last
decoded buffer with data.

Subject: media: tm6000: cleanup trival coding style issues

- Delete seven error messages for a failed memory allocation
- Adjust seven checks for null pointers
- Use common error handling code in tm6000_usb_probe()
- Adjust jump targets so that the function "kfree" will be always called
  with a non-null pointer.
- Delete an initialisation for the local variable "dev"
  which became unnecessary with this refactoring.

Also, make the declaration in the header const.

Subject: media: au0828/em28xx: make vb2_ops const

Make vb2_ops const as they are only stored in the const field of a
vb2_queue structure. Make the declarations const too.

Done using Coccinelle.

We can remove the check for if "state->cec_adap" is NULL.  The
cec_allocate_adapter() function never returns NULL and also we verified
that "state->cec_adap" is an error pointer.

+* Sony 1/2.5-Inch 8.51Mp CMOS Digital Image Sensor
+
+The Sony imx274 is a 1/2.5-inch CMOS active pixel digital image sensor with
+an active array size of 3864H x 2202V. It is programmable through I2C
+interface. The I2C address is fixed to 0x1a as per sensor data sheet.
+Image data is sent through MIPI CSI-2, which is configured as 4 lanes
+at 1440 Mbps.
+
+
+Required Properties:
+- compatible: value should be "sony,imx274" for imx274 sensor
+- reg: I2C bus address of the device
+
+Optional Properties:
+- reset-gpios: Sensor reset GPIO
+
+The imx274 device node should contain one 'port' child node with
+an 'endpoint' subnode. For further reading on port node refer to
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
+	sensor@1a {
+		compatible = "sony,imx274";
+		reg = <0x1a>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		reset-gpios = <&gpio_sensor 0 0>;
+		port {
+			sensor_out: endpoint {
+				remote-endpoint = <&csiss_in>;

Subject: media: staging: atomisp: Add driver prefix to Kconfig option and
 module names

By adding the "atomisp-" prefix to module names (and "ATOMISP_" to Kconfig
options), the staging drivers for e.g. sensors are labelled as being
specific to atomisp, which they effectively are.

Subject: media: staging: atomisp: Update TODO regarding sensors

There was no specific item regarding what should be done to sensor, lens
and flash drivers. Add one, to replace the vague item denoting support
only to particular sensor, lens and flash devices.

+9. Switch to standard V4L2 sub-device API for sensor and lens. In

Subject: media: staging/atomisp: make six local functions static to appease
 sparse

The functions __bo_alloc, __bo_search_and_remove_from_free_rbtree,
__bo_search_by_addr, __bo_search_by_addr_in_range, __bo_break_up and
__bo_merge  are local to the source and do not need to be in the global
scope, so make them static.

Cleans up sparse warnings:

warning: symbol '__bo_alloc' was not declared. Should it be static?
warning: symbol '__bo_search_and_remove_from_free_rbtree' was not declared. Should it be static?
warning: symbol '__bo_search_by_addr' was not declared. Should it be static?
warning: symbol '__bo_search_by_addr_in_range' was not declared. Should it be static?
warning: symbol '__bo_break_up' was not declared. Should it be static?
warning: symbol '__bo_merge' was not declared. Should it be static?

+* Tegra HDMI CEC hardware
+
+The HDMI CEC module is present in Tegra SoCs and its purpose is to
+handle communication between HDMI connected devices over the CEC bus.
+
+Required properties:
+  - compatible : value should be one of the following:
+	"nvidia,tegra114-cec"
+	"nvidia,tegra124-cec"
+	"nvidia,tegra210-cec"
+  - reg : Physical base address of the IP registers and length of memory
+	  mapped region.
+  - interrupts : HDMI CEC interrupt number to the CPU.
+  - clocks : from common clock binding: handle to HDMI CEC clock.
+  - clock-names : from common clock binding: must contain "cec",
+		  corresponding to the entry in the clocks property.
+  - hdmi-phandle : phandle to the HDMI controller, see also cec.txt.
+
+Example:
+
+cec@70015000 {
+	compatible = "nvidia,tegra124-cec";
+	reg = <0x0 0x70015000 0x0 0x00001000>;
+	interrupts = <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>;
+	clocks = <&tegra_car TEGRA124_CLK_CEC>;
+	clock-names = "cec";

Subject: media: tegra-cec: add Tegra HDMI CEC driver

This driver adds support for the Tegra CEC IP. It is based on the
NVIDIA drivers/misc/tegra-cec driver in their 3.10 kernel.

This has been converted to the CEC framework and cleaned up.

Tested with my Jetson TK1 board. It has also been tested with the
Tegra X1 in an embedded product.

Note of warning for the Tegra X2: this SoC supports two HDMI outputs,
but only one CEC adapter and the CEC bus is shared between the
two outputs. This is a design mistake and the CEC adapter can
control only one HDMI output. Never hook up both HDMI outputs
to the CEC bus in a hardware design: this is illegal as per the
CEC specification.

The CEC bus can be shared between multiple inputs and zero or one
outputs, but not between multiple outputs.

Subject: media: i2c: OV5647: ensure clock lane in LP-11 state before streaming
 on

When I was supporting Rpi Camera Module on the ASUS Tinker board,
I found this driver have some issues with rockchip's mipi-csi driver.
It didn't place clock lane in LP-11 state before performing
D-PHY initialisation.

>From our experience, on some OV sensors,
LP-11 state is not achieved while BIT(5)-0x4800 is cleared.

So let's set BIT(5) and BIT(0) both while not streaming, in order to
coax the clock lane into LP-11 state.

0x4800 : MIPI CTRL 00
	BIT(5) : clock lane gate enable
		0: continuous
		1: none-continuous
	BIT(0) : manually set clock lane
		0: Not used
		1: used

Subject: media: staging: media: atomisp: Fix oops by unbalanced clk
 enable/disable call

The common-clk core expects clk consumers to always call enable/disable
in a balanced manner. The atomisp driver does not call gmin_flisclk_ctrl()
in a balanced manner, so add a clock_on bool and skip redundant calls.

This fixes kernel oops like this one:

Subject: media: staging: atomisp2: cleanup null check on memory allocation

For memory allocation functions that fail with a NULL return value, it
is preferred to use the (!x) test in place of (x == NULL).

Changes in atomisp2/css2400/sh_css.c were done by hand.

Done with the help of the following cocci script:

@@
type T;
T* p;
statement s,s1;
@@

p =
  \(devm_kzalloc\|devm_ioremap\|usb_alloc_urb\|alloc_netdev\|dev_alloc_skb\|
   kmalloc\|kmalloc_array\|kzalloc\|kcalloc\|kmem_cache_alloc\|kmem_cache_zalloc\|
   kmem_cache_alloc_node\|kmalloc_node\|kzalloc_node\|devm_kzalloc\)(...)
...when != p

if (
- p == NULL
+ !p
 ) s
 else s1

--
Changes in v3:
  Rebase changes over atomisp-next branch of the media tree
Changes in atomisp2/css2400/sh_css.c were done by hand, the above script
was not able to match the pattern if (a->b != null).

From: Kees Cook
Date: Wed, 4 Oct 2017 20:47:38 -0400
Subject: media: staging: atomisp: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly.

From: Andy Shevchenko

Subject: media: staging: atomisp: Remove IMX sensor support

This sensor is not used by any known ACPI-enabled platform
(and no kernel users for it so far).

Just remove it for good until we get a platform which actually uses it.

- * ISP Scaling is now supported in online capture use cases. Because of that

Subject: media: staging: atomisp: Remove AP1302 sensor support

This sensor is not used by any known ACPI-enabled platform
(and no kernel users for it so far).

Just remove it for good until we get a platform which actually uses it.

From e19c92059a700453a304061ff4291dfc2de2902b Mon Sep 17 00:00:00 2001
From: Andy Shevchenko
Date: Wed, 27 Sep 2017 14:24:59 -0400
Subject: media: staging: atomisp: Switch i2c drivers to use ->probe_new()

Since most of the drivers are being used on ACPI enabled platforms
there is no need to keep legacy API support for them. Thus, switch
to ->probe_new() callback and remove orphaned code.

Subject: media: staging: atomisp: Do not set GPIO twice

gpiod_get() configures GPIO line at the time of successful request.
Thus, no need to do this explicitly.

Subject: media: staging: atomisp: Remove ->gpio_ctrl() callback

There is redundant callback which does nothing in upstreamed version of
the driver.

Remove it along with user call places.

Mostly done with help of coccinelle.

Subject: media: staging: atomisp: Remove ->power_ctrl() callback

There is redundant callback which does nothing in upstreamed version of
the driver.

Remove it along with user call places.

Mostly done with help of coccinelle.

Subject: media: staging: atomisp: Remove FSF snail address

Snail address is subject to change, remove it completely from the code.

This has been done using the following script:

	sed -i '/You should/,/02110-1301/d' \
		$(git grep -n -w Franklin -- drivers/staging/media/atomisp/ | cut -f1 -d:)

No functional change intended.

Subject: media: staging: atomisp: Add videobuf2 switch to TODO

The atomisp driver uses the videobuf1 framework for buffer management. The
framework is being removed; switch to videobuf2 needs to be made. There
are only a handful of remaining non-staging drivers using videobuf1.

Make this const as it is only passed to the const argument of the

Also, make the declaration in the header const.

Subject: media: radio-si470x: make si470x_viddev_template const

Make this const as it is only used in a copy operation in the files
referencing it. Add const to declaration in the header too.

Structure found using Coccienlle and changes done by hand.

Subject: media: media/saa7146: Convert timers to use timer_setup()

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
to pass the timer pointer explicitly. This requires adding a pointer to
hold the timer's target file, as there won't be a way to pass this in the
future.

Subject: media: davinci: make function arguments const

Make the function arguments of functions vpfe_{register/unregister}_ccdc_device
const as the pointer dev does not modify the fields of the structure
it points to. Also, declare the variable ccdc_dev const as it points to the
same structure as dev but it does not modify the fields as well.

Subject: media: v4l2-ctrl: Fix flags field on Control events

VIDIOC_DQEVENT and VIDIOC_QUERY_EXT_CTRL should give the same output for
the control flags field.

This patch creates a new function user_flags(), that calculates the user
exported flags value (which is different than the kernel internal flags
structure). This function is then used by all the code that exports the
internal flags to userspace.

Subject: media: rockchip/rga: annotate PM functions as __maybe_unused

The newly added driver has incorrect #ifdef annotations on its
PM functions, leading to a harmless compile-time warning when
CONFIG_PM is disabled:

drivers/media/platform/rockchip/rga/rga.c:760:13: error: 'rga_disable_clocks' defined but not used [-Werror=unused-function]
 static void rga_disable_clocks(struct rockchip_rga *rga)
             ^~~~~~~~~~~~~~~~~~
drivers/media/platform/rockchip/rga/rga.c:728:12: error: 'rga_enable_clocks' defined but not used [-Werror=unused-function]

This removes the #ifdef and marks the functions as __maybe_unused,
so gcc can silently drop all the unused code.

Fixes: f7e7b48e6d79 ("[media] rockchip/rga: v4l2 m2m support")

Subject: media: tegra-cec: fix messy probe() cleanup

The probe() cleanup code ('goto foo_error') was very messy. It appears
that this code wasn't updated when I switched to the devm_ functions
in an earlier version.

Update the code to use 'return error' where it can and do proper cleanup
where it needs to.

Note that the original code wasn't buggy, it was just messy.

Subject: media: usbtv: fix brightness and contrast controls

Because the brightness and contrast controls share a register,
usbtv_s_ctrl needs to read the existing values for both controls before
inserting the new value. However, the code accidentally wrote to the
registers (from an uninitialised stack array), rather than reading them.

The user-visible effect of this was that adjusting the brightness would
also set the contrast to a random value, and vice versa -- so it wasn't
possible to correctly adjust the brightness of usbtv's video output.

Tested with an "EasyDAY" UTV007 device.

Fixes: c53a846c48f2 ("usbtv: add video controls")

Subject: media: radio-raremono: remove redundant initialization of freq

Variable freq is initialized to f->frequency however this value
is never read and freq is later updated; hence the initialization
is redundant and can be removed.

Cleans up clang warning:

The v4l2_i2c_subdev_init() sets V4L2_SUBDEV_FL_IS_I2C flag in the
subdev->flags.  But this driver overwrites subdev->flags immediately after
calling v4l2_i2c_subdev_init().  So V4L2_SUBDEV_FL_IS_I2C is not set after
all.

This stops breaking subdev->flags and preserves V4L2_SUBDEV_FL_IS_I2C.

Side note: According to the comment in v4l2_device_unregister(), this is
problematic only if the device is platform bus device.  Device tree or
ACPI based devices are not affected.

 array

The test_pattern_menu[] array has two valid items and a null terminated
item.  So the control's maximum value which is passed to
v4l2_ctrl_new_std_menu_items() should be one.  However,
'ARRAY_SIZE(test_pattern_menu) - 1' is actually passed and it's not
correct.

Fix it by removing unnecessary terminated entry and let the correct
control's maximum value be passed to v4l2_ctrl_new_std_menu_items().

Subject: media: v4l: async: Remove re-probing support

Remove V4L2 async re-probing support. The re-probing support has been
there to support cases where the sub-devices require resources provided by
the main driver's hardware to function, such as clocks.

Reprobing has allowed unbinding and again binding the main driver without
explicitly unbinding the sub-device drivers. This is certainly not a
common need, and the responsibility will be the user's going forward.

An alternative could have been to introduce notifier specific locks.
Considering the complexity of the re-probing and that it isn't really a
solution to a problem but a workaround, remove re-probing instead.

If there is a need to support the clock provider unregister/register cycle
while keeping the clock references in the consumers in the future, this
should be implemented in the clock framework instead, not in V4L2.

Subject: media: v4l: async: Don't set sd->dev NULL in v4l2_async_cleanup

v4l2_async_cleanup() is called when the async sub-device is unbound from
the media device. As the pointer is set by the driver registering the
async sub-device, leave the pointer as set by the driver.

 v4l2_async_notifier_unregister()

The call to v4l2_async_cleanup() will set sd->asd to NULL so passing it to
notifier->unbind() has no effect and leaves the notifier confused. Call
the unbind() callback prior to cleaning up the subdevice to avoid this.

The notifier complete callback may return an error. This error code was
simply returned to the caller but never handled properly.

Move calling the complete callback function to the caller from
v4l2_async_test_notify and undo the work that was done either in async
sub-device or async notifier registration.

Subject: media: v4l: async: Correctly serialise async sub-device
 unregistration

The check whether an async sub-device is bound to a notifier was performed
without list_lock held, making it possible for another process to
unbind the async sub-device before the sub-device unregistration function
proceeds to take the lock.

Fix this by first acquiring the lock and then proceeding with the check.

Subject: media: v4l: fwnode: Support generic parsing of graph endpoints in a
 device

Add two functions for parsing devices graph endpoints:
v4l2_async_notifier_parse_fwnode_endpoints and
v4l2_async_notifier_parse_fwnode_endpoints_by_port. The former iterates
over all endpoints whereas the latter only iterates over the endpoints in
a given port.

The former is mostly useful for existing drivers that currently implement
the iteration over all the endpoints themselves whereas the latter is
especially intended for devices with both sinks and sources: async
sub-devices for external devices connected to the device's sources will
have already been set up, or the external sub-devices are part of the
master device.

Depends-on: ("device property: preserve usecount for node passed to of_fwnode_graph_get_port_parent()")

From: Sakari Ailus

Subject: media: rcar-vin: Use generic parser for parsing fwnode endpoints

Instead of using a custom driver implementation, use
v4l2_async_notifier_parse_fwnode_endpoints() to parse the fwnode endpoints
of the device.

Subject: media: omap3isp: Fix check for our own sub-devices

We only want to link sub-devices that were bound to the async notifier the
isp driver registered but there may be other sub-devices in the
v4l2_device as well. Check for the correct async notifier.

From: Laurent Pinchart
Date: Wed, 30 Aug 2017 13:18:04 -0400
Subject: media: v4l: async: Move async subdev notifier operations to a
 separate structure

The async subdev notifier .bound(), .unbind() and .complete() operations
are function pointers stored directly in the v4l2_async_subdev
structure. As the structure isn't immutable, this creates a potential
security risk as the function pointers are mutable.

To fix this, move the function pointers to a new
v4l2_async_subdev_operations structure that can be made const in
drivers.

Subject: media: v4l: async: Introduce helpers for calling async ops callbacks

Add three helper functions to call async operations callbacks. Besides
simplifying callbacks, this allows async notifiers to have no ops set,
i.e. it can be left NULL.

Subject: media: v4l: async: Register sub-devices before calling bound callback

Register the sub-device before calling the notifier's bound callback.
Doing this the other way around is problematic as the struct v4l2_device
has not assigned for the sub-device yet and may be required by the bound
callback.

Subject: media: v4l: async: Allow async notifier register call succeed with no
 subdevs

The information on how many async sub-devices would be bindable to a
notifier is typically dependent on information from platform firmware and
it's not driver's business to be aware of that.

Many V4L2 main drivers are perfectly usable (and useful) without async
sub-devices and so if there aren't any around, just proceed call the
notifier's complete callback immediately without registering the notifier
itself.

If a driver needs to check whether there are async sub-devices available,
it can be done by inspecting the notifier's num_subdevs field which tells
the number of async sub-devices.

Refactor the V4L2 async framework a little in preparation for async
sub-device notifiers. This avoids making some structural changes in the
patch actually implementing sub-device notifiers, making that patch easier
to review.

From 2cab00bb076b9f0e8442e3d72425843d2b441143 Mon Sep 17 00:00:00 2001
From: Sakari Ailus

Subject: media: v4l: async: Allow binding notifiers to sub-devices

Registering a notifier has required the knowledge of struct v4l2_device
for the reason that sub-devices generally are registered to the
v4l2_device (as well as the media device, also available through
v4l2_device).

This information is not available for sub-device drivers at probe time.

What this patch does is that it allows registering notifiers without
having v4l2_device around. Instead the sub-device pointer is stored in the
notifier. Once the sub-device of the driver that registered the notifier
is registered, the notifier will gain the knowledge of the v4l2_device,
and the binding of async sub-devices from the sub-device driver's notifier
may proceed.

The complete callback of the root notifier will be called only when the
v4l2_device is available and no notifier has pending sub-devices to bind.
No complete callbacks are supported for sub-device notifiers.

Subject: media: v4l: async: Ensure only unique fwnodes are registered to
 notifiers

While registering a notifier, check that each newly added fwnode is
unique, and return an error if it is not. Also check that a newly added
notifier does not have the same fwnodes twice.

Subject: media: v4l: fwnode: Move KernelDoc documentation to the header

In V4L2 the practice is to have the KernelDoc documentation in the header
and not in .c source code files. This consequently makes the V4L2 fwnode
function documentation part of the Media documentation build.

Also correct the link related function and argument naming in
documentation and add an asterisk to v4l2_fwnode_endpoint_free()
documentation to make it proper KernelDoc documentation.

+ *
+ * First find an fwnode referred to by the reference at @index in @prop.
+ *
+ * Then under that fwnode, @nprops times, for each property in @props,
+ * iteratively follow child nodes starting from fwnode such that they have the
+ * property in @props array at the index of the child node distance from the
+ * root node and the value of that property matching with the integer argument
+ * of the reference, at the same index.
+ *
+ * The child fwnode reched at the end of the iteration is then returned to the
+ * caller.
+ *
+ * The core reason for this is that you cannot refer to just any node in ACPI.
+ * So to refer to an endpoint (easy in DT) you need to refer to a device, then
+ * provide a list of (property name, property value) tuples where each tuple
+ * uniquely identifies a child node. The first tuple identifies a child directly
+ * underneath the device fwnode, the next tuple identifies a child node
+ * underneath the fwnode identified by the previous tuple, etc. until you
+ * reached the fwnode you need.
+ *
+ * An example with a graph, as defined in Documentation/acpi/dsd/graph.txt:

Subject: media: v4l: fwnode: Add convenience function for parsing common
 external refs

Add v4l2_fwnode_parse_reference_sensor_common for parsing common
sensor properties that refer to adjacent devices such as flash or lens
driver chips.

As this is an association only, there's little a regular driver needs to
know about these devices as such.

Subject: media: v4l: fwnode: Add a convenience function for registering
 sensors

Add a convenience function for parsing firmware for information on related
devices using v4l2_async_notifier_parse_fwnode_sensor_common() registering
the notifier and finally the async sub-device itself.

This should be useful for sensor drivers that do not have device specific
requirements related to firmware information parsing or the async
framework.

Subject: media: smiapp: Add support for flash and lens devices

Parse async sub-devices related to the sensor by switching the async
sub-device registration function.

These types devices aren't directly related to the sensor, but are
nevertheless handled by the smiapp driver due to the relationship of these
component to the main part of the camera module --- the sensor.

This does not yet address providing the user space with information on how
to associate the sensor or lens devices but the kernel now has the
necessary information to do that.

Subject: media: v4l2-fwnode: use the cached value instead of getting again

There is a get/put operation in order to get firmware is_available
data there at the __v4l2_async_notifier_parse_fwnode_endpoints()
function. However, instead of using it, the code just reads again
without the lock. That's a bug, as dev_fwnode isn't guaranteed
to be there once fwnode_handle_put() has been called on it.

This solves this smatch warning:

drivers/media/v4l2-core/v4l2-fwnode.c:453:8: warning: variable 'is_available' set but not used [-Wunused-but-set-variable]
   bool is_available;

On lots of places, assert/return are starting at the first

drivers/staging/media/atomisp/pci/atomisp2/css2400/hive_isp_css_common/host/irq_private.h:32 irq_reg_store() warn: inconsistent indenting

Used this small script to fix such occurrences:

Subject: media: atomisp: get rid of wrong stddef.h include

The places at atomisp.h that use stddef.h are wrong: the
types it needs are actually defined at linux/types.h. Also,
it causes lots of smatch warnings due to the redefinition of
ofsetof() macro:

/opt/gcc-7.1.0/x86/lib/gcc/x86_64-pc-linux-gnu/7.1.0/include/stddef.h:417:9: warning: preprocessor token offsetof redefined
./include/linux/stddef.h:16:9: this was the original definition

Subject: media: camss-vfe: always initialize reg at vfe_set_xbar_cfg()

if output->wm_num is bigger than 2, the value for reg is
not initialized, as warned by smatch:
	drivers/media/platform/qcom/camss-8x16/camss-vfe.c:633 vfe_set_xbar_cfg() error: uninitialized symbol 'reg'.
	drivers/media/platform/qcom/camss-8x16/camss-vfe.c:637 vfe_set_xbar_cfg() error: uninitialized symbol 'reg'.

That shouldn't happen in practice, so add a logic that will
break the loop if i > 1, fixing the warnings.

Subject: media: imx274: fix missing return assignment from call to
 imx274_mode_regs

The variable ret is being checked for failure however it is not being set
from the return status from the call to imx274_mode_regs. Currently ret is
alwayus zero and the check is redundant. Fix this by assigning it.

Subject: media: v4l: async: fix return of unitialized variable ret

A shadow declaration of variable ret is being assigned a return error
status and this value is being lost when the error exit goto's jump
out of the local scope. This leads to an uninitalized error return value
in the outer scope being returned. Fix this by removing the inner scoped
declaration of variable ret.

Subject: media: v4l: async: fix unregister for implicitly registered
 sub-device notifiers

The commit aef69d54755d45ed ("media: v4l: fwnode: Add a convenience
function for registering sensors") adds the function
v4l2_async_notifier_parse_fwnode_sensor_common() to parse and register a
subdevice and a subdev-notifier by parsing firmware information. This
new subdev-notifier is stored in the new field 'subdev_notifier' in
struct v4l2_subdev.

In v4l2_async_unregister_subdev() this field is used to unregister and
cleanup the subdev-notifier. A check for if the subdev-notifier is
initialized or not was forgotten leading to a NULL pointer dereference
in v4l2_async_notifier_cleanup() if a subdevice do not use the optional
convince function to initialize the field.

Fix this by checking in v4l2_async_notifier_cleanup() that it is
provided whit a notifier making it safe to call with a NULL parameter.

Using the deprecated do_gettimeofday() in print_time() will overflow
in 2038 on 32-bit architectures. It'sbetter to use a structure that
is safe everywhere. While we're at it, fix the missing leading zeroes
on the sub-second portion.

Subject: media: dvb-core: always call invoke_release() in fe_free()

Follow-up to: ead666000a5f ("media: dvb_frontend: only use kref after initialized")

The aforementioned commit fixed refcount OOPSes when demod driver attaching
succeeded but tuner driver didn't. However, the use count of the attached
demod drivers don't go back to zero and thus couldn't be cleanly unloaded.
Improve on this by calling dvb_frontend_invoke_release() in
__dvb_frontend_free() regardless of fepriv being NULL, instead of returning
when fepriv is NULL. This is safe to do since _invoke_release() will check
for passed pointers being valid before calling the .release() function.

[mchehab@s-opensource.com: changed the logic a little bit to reduce
 conflicts with another bug fix patch under review]

Subject: media: dib0700: fix invalid dvb_detach argument

dvb_detach(arg) calls symbol_put_addr(arg), where arg should be a pointer
to a function. Right now a pointer to state->dib7000p_ops is passed to
dvb_detach(), which causes a BUG() in symbol_put_addr() as discovered by
syzkaller. Pass state->dib7000p_ops.set_wbd_ref instead.

Subject: dvb_frontend: don't use-after-free the frontend struct

dvb_frontend_invoke_release() may free the frontend struct.
So, the free logic can't update it anymore after calling it.

That's OK, as __dvb_frontend_free() is called only when the
krefs are zeroed, so nobody is using it anymore.

That should fix the following KASAN error:

The KASAN report looks like this (running on kernel 3e0cc09a3a2c40ec1ffb6b4e12da86e98feccb11 (4.14-rc5+)):
