Since ARGB was the selected format for connecting the frontend to the

3. nonblocking disable crtc
On i915 this can lead to a spurious -EBUSY from step 3 on
account of non-enabled planes getting the fake_commit in step 1

drm_atomic_helper_commit_hw_done() which can happen a long
time after the flip event was sent out.
This will become somewhat easy to hit on SKL+ once we start
to add all the planes for the crtc to every modeset commit
for the purposes of forcing a watermark register programming
[1].
To make the race a little less pronounced let's complete
fake_commit->flip_done after drm_atomic_helper_wait_for_flip_done().
For the single crtc case this should make the race quite
theoretical, assuming drm_atomic_helper_wait_for_flip_done()
actually has to wait for the real commit flip_done. In case
the real commit flip_done gets completed singificantly before
drm_atomic_helper_wait_for_flip_done(), or we are dealing with

qxl: Make sure qxl_cursor memory is pinned

memory is not.
When booting a recent Fedora to its login screen while monitoring the

that QXLCursor memory is not going to be moved by the guest kernel.
Moving the pin/unpin to qxl_release_list_add()/qxl_release_free_list()

drm/bridge/sii902x: Fix EDID readback
While adding SiI9022A support to the iwg23s board, it came
up that when the HDMI transmitter is in pass through mode the
device is not compliant with the I2C specification anymore,
as it requires a far bigger tbuf, due to a delay the HDMI
transmitter is adding when relaying the STOP condition on the
monitor i2c side of things.
When not providing an appropriate delay after the STOP condition
the i2c bus would get stuck. Also, any other traffic on the bus
while talking to the monitor may cause the transaction to fail
or even cause issues with the i2c bus as well.
I2c-gates seemed to reach consent as a possible way to address
these issues, and as such this patch is implementing a solution
based on that. Since others are clearly relying on the current
implementation of the driver, this patch won't require any DT
changes.
Since we don't want any interference during the DDC Bus
Request/Grant procedure and while talking to the monitor, we
have to use the adapter locking primitives rather than the
i2c-mux locking primitives.

the timings are expressed by the hardware, not put into the

Further the device was incorrectly modeled with GPIO lines

- lower the OSD rendering
- lower the memory usage
This use-case is used when setting the display mode to 3840x2160 and the

drm/vc4: ->x_scaling[1] should never be set to VC4_SCALING_NONE
For the YUV conversion to work properly, ->x_scaling[1] should never
be set to VC4_SCALING_NONE, but vc4_get_scaling_mode() might return
VC4_SCALING_NONE if the horizontal scaling ratio exactly matches the
horizontal subsampling factor. Add a test to turn VC4_SCALING_NONE
into VC4_SCALING_PPF when that happens.
The old ->x_scaling[0] adjustment is dropped as I couldn't find any
mention to this constraint in the spec and it's proven to be
unnecessary (I tested various multi-planar YUV formats with scaling
disabled, and all of them worked fine without this adjustment).

DesignWare HDMI PHY.
Add binding for it.

drm/sun4i: Not all DW HDMI controllers has scrambled addresses
Currently supported Allwinner SoCs with DW HDMI controller have
scrambled addresses and read lock. However, that is not true in general.
For example, A80 and H6 have normal addresses and normal read access.
Move code for unscrambling addresses and unlocking read access to it's
own function and call it from init function.
