The Hitachi tx18d42vm LCD panel driver is really just initialising the
device, using bitbanged SPI, during operation there is nothing to do.
This makes the driver self contained, so drop the bogus dependency on
the legacy CONFIG_VIDEO.
This avoids the warning when building Chuwi_V7_CW0825_defconfig, since
we switched to DM_VIDEO recently.

The U-Boot port for ST-Ericsson Ux500 is currently only used on the
"stemmy" board, where U-Boot runs after firmware that already sets up
a boot splash screen. This means that the display is already on
and we can just continue using it for U-Boot.
Add a simple driver that simplifies this by reading the display
configuration (e.g. screen size, bpp) from the hardware registers.
It also checks the configured "source synchronization" - for some
displays (usually DSI command mode displays) we need to explicitly
trigger a software sync. This is done through the video_sync()
callback that triggers the sync and wait for completion.

make sense to store it in driver private data since it's already stored

Each row in the pixel array in the bitmap file is padded
if necessary so the row size is always a multiple of 4 bytes.
In current code the complement of row size to a multiple of
4 bytes is further unnecessarily multiplied by the pixel size.
This results in incorrect displaying of bitmaps having row size
that is not a multiple of 4 bytes. Fix this by removing
the unnecessary multiplication.

The PWM device provided by Chrome OS EC doesn't really support anything
other than setting a relative duty cycle. To support it as a backlight,
this patch makes the PWM period optional in the device tree and pretends
the valid brightness range is its period_ns.
Also adds a sandbox test for a PWM channel that has a fixed period,
checking that the resulting duty_cycle matches on a set_config() even if
the requested period_ns can't be set.

The current code is using an hard coded enum and the of node reg value of
endpoint to find out if the endpoint is mipi/hdmi/lvds/edp/dp. The order
is different between rk3288, rk3399 vop little, rk3399 vop big.
A possible solution would be to make sure that the rk3288.dtsi and
rk3399.dtsi files have "expected" reg value or an other solution is
to find the kind of endpoint by comparing the endpoint compatible value.
This patch is implementing the more flexible second solution.

for both cases.

Failure to update by the deadline may result in board removal.
