[Intel-gfx] [PATCH 00/59] Add support for Keem Bay DRM driver

[Anitha Chrisanthus]

This is a new DRM driver for Intel's KeemBay SOC.
The SoC couples an ARM Cortex A53 CPU with an Intel
Movidius VPU.

This driver is tested with the KMB EVM board which is the refernce baord
for Keem Bay SOC. The SOC's display pipeline is as follows

+--------------+    +---------+    +-----------------------+
|LCD controller| -> |Mipi DSI | -> |Mipi to HDMI Converter |
+--------------+    +---------+    +-----------------------+

LCD controller and Mipi DSI transmitter are part of the SOC and 
mipi to HDMI converter is ADV7535 for KMB EVM board.

The DRM driver is a basic KMS atomic modesetting display driver and
has no 2D or 3D graphics.It calls into the ADV bridge driver at 
the connector level.

Only 1080p resolution and single plane is supported at this time.
The usecase is for debugging video and camera outputs.

Since we are just starting the upstream process, the KMB EVM board is not in
mainline and so Device tree changes are missing.
