imx doesn't have any functions for setting the gamma table, so this is
completely defunct.
Not nice to lie to userspace, so let's stop!

Just as the function ipu_dmfc_config_wait4eot() tells, the DMFC wait4eot bit
depends on the number of DMFC slots to be used, so it should be called after
the slots are determined in the function ipu_dmfc_alloc_bandwidth().
Based on tests, this patch may eliminate display distortion issue on overlay
plane with small resolutions. To reproduce the issue, we may run this drm
modetest case - 'modetest -P 19:64x64'.

The function name 'ipu_dmfc_config_wait4eot' matches the implementation of
the function better than 'ipu_dmfc_init_channel', since it only touches the
wait4eot bits.

Since the function ipu_dmfc_init_channel() always returns zero, we may

The IMX dw_hdmi driver just called platform_set_drvdata() to get
your hopes up that maybe, somehow, you'd be able to retrieve the 'struct
imx_hdmi' from a pointer to the 'struct device'. You can't. When
we call dw_hdmi_bind() the main driver calls dev_set_drvdata(), which
clobbers our setting.
Let's just remove the platform_set_drvdata() to avoid dashing people's
hopes.

The drm_encoder_cleanup() was missing both from the error path of
dw_hdmi_imx_bind(). This caused a crash when slub_debug was
enabled and we ended up deferring probe of HDMI at boot.
This call isn't needed from unbind() because if dw_hdmi_bind() returns
no error then it takes over the job of freeing the encoder (in
dw_hdmi_unbind).

The IPU addresses multiplanar formats using a base address and relative
offsets for the secondary planes. Since those offsets must be positive
and not too large, and none of the plane parameters except the base address
may be changed while scanout is active, store the pitches and u/v offsets
and check all values against IDMAC limitations.

If the FB is backed by a GEM object with an dma-buf attached
we need to wait for any pending fences to signal before executing
the page flip.
The implementation is straight forward by deferring the flip to
a workqueue in that case.

The DRM core only references the currently queued/active framebuffer.
So there is a period of time where the flip is not completed, but
the GEM object backing the FB is already unreferenced and could be
destroyed if userspace closes its handle.
Make sure to keep a reference to the GEM object until the flip is
actually executed clean things up in a worker running behind the
flip execution.
Also move the page flip event into the context of this worker, so
it gets cleaned up automatically.

So this one is special, since it tries to prevent races when userspace
crashes simply by disabling the vblank machinery. Well except that imx
always has vblanks enabled, and the disable_vblank hook actually just
tries to cancel a pending pageflip. Without any locking whatsoever. Of
course this is wrong, since it'll result in the hw not actually
displaying what drm thinks is the current frontbuffer.
Well since the core takes care of the disappearing DRM fd now. So we
can nuke all this confused code without ill side-effects.
Someone else needs to audit the locking for ->newfb and
->page_flip_event and fix it up. Common approach is to reuse
dev->event_lock for this.

The drm_fbdev_cma_init function always calls the
drm_helper_disable_unused_functions. Since it's part of the usual probe
process, all the drivers using that helper will end up having their encoder
and CRTC disable functions called at probe if their device has not been
reported as enabled.
This could be fixed by reading out from the registers the current state of
the device if it is enabled, but even that will not handle the case where
the device is actually disabled.
Moreover, the drivers using the atomic modesetting expect that their enable
and disable callback to be called when the device is already enabled or
disabled (respectively).
We can however fix this issue by moving the call to
drm_helper_disable_unused_functions out of drm_fbdev_cma_init and make the
drivers needing it (all the drivers calling drm_fbdev_cma_init and not
using the atomic modesetting) explicitly call it.

An encoder is associated with a connector by the DRM core as a result of
setting up a configuration. Drivers using the atomic or legacy helpers
should never set up this link, even if it is a static one.
While at it, try to catch this kind of error in the future by adding a
WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't
cover all the cases, since drivers could set this up after attaching.
Drivers that use the atomic helpers will get a warning later on, though,
so hopefully the two combined cover enough to help people avoid this in
the future.

ipu_crtc_handle_pageflip() was calling drm_send_vblank_event() with
a pipe argument of -1. Commit cc1ef118fc09 ("drm/irq: Make pipe
unsigned and name consistent") now makes this error obvious, as we
now may get a warning from:
if (WARN_ON(pipe >= dev->num_crtcs))
in drm_vblank_count_and_time(). Prior to this change, we would end
up making out-of-bounds array accesses via:
struct drm_vblank_crtc *vblank = &dev->vblank[crtc];
and
*vblanktime = vblanktimestamp(dev, pipe, cur_vblank);
So, this has been broken for a very long time, and is not a result
of the above commit. Since we don't care about the staging versions,
I've tagged this with the earliest mainline commit where we do care,
even though this commit did not introduce the bug.

Use drm_universal_plane_init to create the planes, create the primary
plane first and use drm_crtc_init_with_planes to associate it with
the crtc.
This gets rid of the unused fallback primary plane previously created
by drm_crtc_init and fixes a NULL pointer dereference issue that can
be triggered by a modeset from userspace when fbdev helpers are
enabled [1].

This worked before the dw-hdmi bridge code was changed to validate
the setup data more strictly. Add back support for modes with a
pixel clock up to 216MHz. Even higher clocks should work, but we
are missing the required setup data for now.
Also change the mode validate callbacks to disallow modes with
higher pixelclocks, so we don't end up failing the modeset later
on.

The generic function is functionally equivalent to the driver's
imx_drm_platform_probe(). Use the generic function and reduce the
overall code size.

drm_vblank_count() returns the software counter. We should not pretend
it's the hw counter since we use the hw counter to figuere out what the
software counter value should be. So instead provide a new function
drm_vblank_no_hw_counter() for drivers that don't have a real hw
counter. The new function simply returns 0, which is about the only
thing it can do.

This continues the pattern started in commit cc1ef118fc09 ("drm/irq:
Make pipe unsigned and name consistent"). This is applied to the public
APIs and driver callbacks, so pretty much all drivers need to be updated
to match the new prototypes.

into drm-next
Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver. This series of patches are based on a couple of dependent
commits from the ALSA tree.
Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
part of the driver.
- clean up the phy configuration: to all lookups before starting to
program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
code)
- remove private hsync/vsync/interlaced flags, getting them from the
DRM mode structure instead.
- implement interface functions to support audio - setting the audio
sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name
These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.

The phy comments in dw_hdmi.c applied to the iMX6 version. Move these
comments to the iMX6 dw_hdmi-imx data along side the data.
