drm/sun4i: backend: Avoid counting YUV planes that use the frontend
Our hardware has a limited number of YUV planes (usually 1) that can be
supported using the backend only. However, YUV planes can also be
supported by the frontend and must then not be counted when checking for
that limitation.
Only count the YUV plane when the frontend is not used.

Before this patch, it is assumed that a plane is supported either

interface does not allow finely reporting our hardware capabilities

In particular, some plane formats are supported by the backend and not
the frontend, so they can only be supported without scaling.

The frontend documentation (for the A33) mentions that ARGB is supported
as output, but with the alpha component always set to 0xff. In practice,
this means that the alpha component cannot be preserved when going
through the frontend. Since the information is lost, ARGB is not
properly supported.
As a result, expose the matching format supported by the frontend (both
for input and output) as XRGB instead of ARGB.
Since ARGB was the selected format for connecting the frontend to the
backend, change it to XRGB to reflect this as well.
The A31 and A80 SoCs apparently have a bit to enable proper alpha,
but this is not supported at this point (see the comment already in 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

[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

When booting a recent Fedora to its login screen while monitoring the

drm/rockchip: fix for mailbox read size
Some of the functions (like cdn_dp_dpcd_read, cdn_dp_get_edid_block)
allow to read 64KiB, but the cdn_dp_mailbox_read_receive, that is
used by them, can read only up to 255 bytes at once. Normally, it's
not a big issue as DPCD or EDID reads won't (hopefully) exceed that
value.
The real issue here is the revocation list read during the HDCP
authentication process. (problematic use case:
https://chromium.googlesource.com/chromiumos/third_party/kernel/+/chromeos-4.4/drivers/gpu/drm/rockchip/cdn-dp-reg.c#1152)
The list can reach 127*5+4 bytes (num devs * 5 bytes per ID/Bksv +
4 bytes of an additional info).
In other words - CTSes with HDCP Repeater won't pass without this
fix. Oh, and the driver will most likely stop working (best case
scenario).

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.

drm/panel: Augment the TPO TPG110 bindings
The TPO TPG110 bindings were using the DPI bindings (popular
in the fbdev subsystem) but this misses the finer points
learned in the DRM subsystem.
We need to augment the bindings for proper DRM integration:
the timings are expressed by the hardware, not put into the
device tree. I.e. this hardware is self-describing and can
report the resolutions and timings needed. It should not
be described in the device tree.
Further the device was incorrectly modeled with GPIO lines
instead of an SPI child, even though the device was using
SPI.
No known deployments of the device using device tree
exist, so it should be fine to augment the bindings.

drm/meson: Add primary plane scaling
This patch adds support for the Primary Plane scaling.
On the Amlogic GX SoCs, the primary plane is used as On-Screen-Display
layer on top of video, and it's needed to keep the OSD layer to a lower
size as the physical display size to :
- lower the memory bandwidth
- lower the OSD rendering
- lower the memory usage
This use-case is used when setting the display mode to 3840x2160 and the
OSD layer is rendered using the GPU. In this case, the GXBB & GXL cannot
work on more than 2000x2000 buffer, thus needing the OSD layer to be kept
at 1920x1080 and upscaled to 3840x2160 in hardware.
The primary plane atomic check still allow 1:1 scaling, allowing native
3840x2160 if needed by user-space applications.

This Overlay plane support various YUV layouts :

- YUV444 / 422 / 420 / 411 / 410
The scaler supports a wide range of scaling ratios, but for simplicity,

The z-order is fixed and always behind the primary plane and cannot be changed.
The scaling parameter algorithm was taken from the Amlogic vendor kernel

drm/sun4i: Add basic support for DE3
Display Engine 3 is an upgrade of DE2 with new features like support for
10 bit color formats and support for AFBC.
Most of DE2 code works with DE3, except some small details.
Implement basic support for DE3. Support for 10 bit colort formats and
AFBC, among others missing features, will be added later.

Most, if not all, registers found in DE2 still exists in DE3. However,
units are on different base addresses.
To prepare for addition of DE3 support, registers macros are reworked so
they take base address as parameter.

dt-bindings: display: sun4i-drm: Add H6 display engine compatibles
This commit adds compatibles used in H6 display pipeline, namely for
display engine, mixer and TV TCON.
H6 display engine is somewhat similar to R40, just less TCONs and
mixer support more features.
