<id>urn:sha1:93e163a9e0392aca7d720491100d810bfc3112b0</id>
<content type='text'>
This patch adds a drm bridge driver for i.MX8qm/qxp pixel combiner.
The pixel combiner takes two output streams from a single display
controller and manipulates the two streams to support a number
of modes(bypass, pixel combine, YUV444 to YUV422, split_RGB) configured
as either one screen, two screens, or virtual screens.  The pixel
combiner is also responsible for generating some of the control signals
for the pixel link output channel.  For now, the driver only supports
the bypass mode.

The driver uses crypto hash functions so it needs to select CRYPTO_HASH.
This fixes build errors:

TI DLPC3433 is a MIPI DSI based display controller bridge
for processing high resolution DMD based projectors.

It has a flexible configuration of MIPI DSI and DPI signal
input that produces a DMD output in RGB565, RGB666, RGB888
formats.

It supports upto 720p resolution with 60 and 120 Hz refresh
rates.

Add bridge driver for it.
