drm: shmobile: Use backlight helper
This started with work on the removal of backlight_properties'
deprecated fb_blank field, much of which can be taken care of by using
helper functions provided by backlight.h instead of directly accessing
fields in backlight_properties. This patch series doesn't involve
fb_blank, but it still seems useful to use helper functions where
appropriate.
Instead of retrieving the backlight brightness in struct
backlight_properties manually, and then checking whether the backlight
should be on at all, use backlight_get_brightness() which does all

drm/bridge: parade-ps8640: Provide wait_hpd_asserted() in struct drm_dp_aux
This implements the callback added by the patch ("drm/dp: Add
wait_hpd_asserted() callback to struct drm_dp_aux").
With this change and all the two "DP AUX Endpoint" drivers changed to
use wait_hpd_asserted(), we no longer need to have an long delay in
the AUX transfer function. It's up to the panel code to make sure that
the panel is powered now. If someone tried to call the aux transfer
function without making sure the panel is powered we'll just get a
normal transfer failure.
We'll still keep the wait for HPD in the pre_enable() function. Though
it's probably not actually needed there, this driver is used in the
old mode (pre-DP AUX Endpoints) and it may be important for those
cases. If nothing else, it shouldn't cause any big problems.
NOTE: When handling the timeout for HPD we start the timer _after_
we've runtime resumed the device. This is definitely important for the
panel on my homestar which comes up 170 ms after we start timing (the
panel specifies 200 ms max). It's a little unclear how much of this
extra time is due to some internal state machine in the parade
firmware vs. debouncing but it seems to work for the two test cases I
have to do it this way.

drm: Config orientation property if panel provides it
Panel orientation property should be set before drm_dev_register().
Some drm driver calls drm_dev_register() in .bind(). However, most
panels sets orientation property relatively late, mostly in .get_modes()
callback, since this is when they are able to get the connector and
binds the orientation property to it, though the value should be known
when the panel is probed.
In drm_bridge_connector_init(), if a bridge is a panel bridge, use it to
set the connector's panel orientation property.

drm/bridge: imx: Add LDB support for i.MX8qm
This patch adds a drm bridge driver for i.MX8qm LVDS display bridge(LDB)
which is officially named as pixel mapper. The LDB has two channels.
Each of them supports up to 30bpp parallel input color format and can
map the input to VESA or JEIDA standards. The two channels can be used
simultaneously, either in dual mode or split mode. In dual mode, the
two channels output identical data. In split mode, channel0 outputs
odd pixels and channel1 outputs even pixels. This patch supports the
LDB single mode and split mode.

But if you run an accelerated fbdev driver and have

drm/bridge: anx7625: Zero error variable when panel bridge not present
While parsing the DT, the anx7625 driver checks for the presence of a
panel bridge on endpoint 1. If it is missing, pdata->panel_bridge stores
the error pointer and the function returns successfully without first
cleaning that variable. This is an issue since other functions later
check for the presence of a panel bridge by testing the trueness of that
variable.
In order to ensure proper behavior, zero out pdata->panel_bridge before
returning when no panel bridge is found.

Revert "fbdev: vesafb: Allow to be built if COMPILE_TEST is enabled"
This reverts commit
fa0e256450f27a7d85f65c63f05e6897954a1d53. The kernel
test robot reported that attempting to build the vesafb driver fails on
some architectures, because these don't define a `struct screen_info`.
This leads to linking errors, for example on parisc with allyesconfig:
hppa-linux-ld: drivers/video/fbdev/vesafb.o: in function `vesafb_probe':
>> (.text+0x738): undefined reference to `screen_info'
>> hppa-linux-ld: (.text+0x73c): undefined reference to `screen_info'
hppa-linux-ld: drivers/firmware/sysfb.o: in function `sysfb_init':
>> (.init.text+0x28): undefined reference to `screen_info'
>> hppa-linux-ld: (.init.text+0x30): undefined reference to `screen_info'
hppa-linux-ld: (.init.text+0x78): undefined reference to `screen_info'
The goal of commit
fa0e256450f2 ("fbdev: vesafb: Allow to be built if
COMPILE_TEST is enabled") was to have more build coverage for the driver
but it wrongly assumed that all architectures would define a screen_info.

drm/edid: fix CTA data block collection size for CTA version 3
The CTA Data Block Collection is valid only for CTA extension version
3. In versions 1 and 2, it is a reserved block, which we ignore.
The DTD start offset (byte 2, or d in CTA-861 spec), which determines
the CTA Data Block Collection size, is specified slightly differently
for different versions:
Version 1:
d = offset for the byte following the reserved data block. If no
data is provided in the reserved data block, then d=4. If no DTDs
are provided, then d=0
Version 2:
d = offset for the byte following the reserved data block. If no
data is provided in the reserved data block, then d=4. If d=0, then
no detailed timing descriptors are provided, and no data is provided
in the reserved data block.
Version 3:
d = offset for the byte following the data block collection. If no
data is provided in the data block collection, then d=4. If d=0,
then no detailed timing descriptors are provided, and no data is
provided in the data block collection.
Ever since commit
9e50b9d55e9c ("drm: edid: Add some bounds checking"),
we've interpreted 0 to mean there are no DTDs but it's all Data
Blocks. Per the spec, Data Blocks are only valid for version 3, where we
should interpret 0 to mean there are no data blocks.
Follow the spec (and hope the EDIDs follow it too).
