When building with Clang + -Wtautological-constant-compare, several of
the ivtv and cx18 drivers warn along the lines of:
drivers/media/pci/cx18/cx18-driver.c:1005:21: warning: converting the
result of '<<' to a boolean always evaluates to true
[-Wtautological-constant-compare]
cx18_call_hw(cx, CX18_HW_GPIO_RESET_CTRL,
^
drivers/media/pci/cx18/cx18-cards.h:18:37: note: expanded from macro
'CX18_HW_GPIO_RESET_CTRL'
#define CX18_HW_GPIO_RESET_CTRL (1 << 6)
^
1 warning generated.
This warning happens because the shift operation is implicitly converted
to a boolean in v4l2_device_mask_call_all before being negated. This can
be solved by just comparing the mask result to 0 explicitly so that
there is no boolean conversion. The ultimate goal is to enable
-Wtautological-compare globally because there are several subwarnings
that would be helpful to have.
For visual consistency and avoidance of these warnings in the future,
all of the implicitly boolean conversions in the v4l2_device macros
are converted to explicit ones as well.

The Hantro G1 decoder is able to enable a post-processor
on the decoding pipeline, which can be used to perform
scaling and color conversion.
The post-processor is integrated to the decoder, and it's
possible to use it in a way that is completely transparent
to the user.
This commit enables color conversion via post-processing,
which means the driver now exposes YUV packed, in addition to NV12.

It has been decided to use the ENUM_FMT index value
as a hint for driver preference. This is defined purposedly
in a very liberal way, letting drivers define what "preference"
means.
For instance, the Hantro VPU driver indicates additional
processing to output a given format, and thus implicates
more CPU usage, which is enumerated after native (non-processed)
formats.

Add support for the sink pad of scaler subdevice to respond
VIDIOC_G_SELECTION and VIDIOC_S_SELECTION ioctls with the following
targets: V4L2_SEL_TGT_COMPOSE_BOUNDS and V4L2_SEL_TGT_CROP.
* Add new const struct crop_rect_default to initialize subdev scaler
properly.
* Make changes in sink pad format reflect to the crop rectangle. E.g.
changing the frame format to a smaller size one can make the former
crop rectangle selects a non existing frame area. To solve this
situation the crop rectangle is clamped to the frame boundaries.
* Clamp crop rectangle respecting the sink bounds during set_selection
ioctl.

When requesting format from sensor, some sensors call the
subdev_get_try_crop which for ISI was not properly initialized, and this
causes errors in determining proper image resolutions.
To accommodate for this, when trying a format (in try_fmt), first attempt
to obtain the framesize for this format from sensor.
In case this fails, use the maximum ISI width/height as try_crop, otherwise
provide the first size height/width from the sensor.

This adds support for GREY and Y16 formats, based on Y10 mbus codes.
Y16 needs to go through preview path in the ISI, with 2 pixels per word,
and it fits the Y16 format. The ISI data lines need to be MSB aligned with
the sensor data lines.
GREY format in 8 bits per pixel is done by dropping the 2 LSB bits
from the Y10 format, and packed as 4 pixels per word.

The ISC can receive input from sensors using Y10 format directly
(10 bits greyscale). In this case, the ISC must dump the data directly,
either as GREY (8bit) or Y10 (10bit).
Y16 is not supported because we cannot align the MSB 10 bits to the MSB
inside the 16bit container.
For this format, the ISC internal pipeline cannot work (only works with
BAYER), so we must dump the data directly as 8bit/10bit.

In case the format that the sensor sends is 8 bit only (like GREY for
example) we need to be able to bypass ISC pipeline and directly dump
8 bits.
That's why the hardcoded value of 16 bpp is not correct in all cases.
This change allows the output format to decide what is the correct bpp
(bits per pixel) such that the result is in the proper format.

When decoding using the CODA internal rotator (for example NV12
capture), currently the value vb2_buf.index + CODA_MAX_FRAMEBUFFERS (19)
is written into the DEC_PIC_ROT_INDEX register. At least with firmware
version 3.1.1 this causes CODA hangups as soon as the register value
reaches 32. Instead, always write CODA_MAX_FRAMEBUFFERS.

This patch adds JPEG encoding support for CODA960, handling the JPEG
hardware directly. A separate JPEG encoder video device is created due
to the separate hardware unit and different supported pixel formats.
While the hardware can not change subsampling on the fly, it can encode
4:2:2 subsampled images into JPEGs of the same subsampling.
There are two additional tracepoints added to the coda driver that can
be used together with the v4l2:v4l2_qbuf and v4l2:v4l2_dqbuf tracepoints
to to follow video frames through the mem2mem device when encoding or
decoding with the CODA960 JPEG codec:
