This demo will demonstrate how to use M7 core to control display on i.MX8MN.

In this demo, generally, we'll add a MIPI-DSI and LCD driver to M7 SDK code and Linux kernel will pass display request to M7 core by rpmsg.

Function:

1. Linux kernel on A core will not handle mipi-dsi and it will send display request to M7 core by RPMSG.

2. M7 core will control MIPI-DSI, LCD and handle display request.

3. When kernel enter sleep, M7 core will show a 1 sec clock (from 0 - 7, updated every second) on screen. (See video for details.)

4. Please read readme.txt and other readme files in patch packages.
