Subject: [LINUX PATCH 0/2] Add Xilinx DSI-Tx DRM driver

MIPI DSI TX subsystem allows you to quickly create systems based on the
MIPI protocol. It interfaces between the video processing subsystems and
MIPI-based displays. An internal high-speed physical layer design, D-PHY,
is provided to allow direct connection to display peripherals.

The subsystem consists of the following sub-blocks:
- MIPI D-PHY
- MIPI DSI TX Controller
- AXI Crossbar

Please refer pg238 [1].

The DSI TX Controller receives stream of image data through an input stream
interface. At design time, this subsystem can be configured to number of lanes
and pixel format.

This patch series adds the dt-binding and DRM driver for Xilinx DSI-Tx soft IP.
