mipi cheat sheet

there are some basic commands in mipi. for example

0x11	exit_sleep_mode	Power for the display panel is on.
0x29	set_display_on	Show the image on the display device.

For full list of general mipi commands, refering the MIPI Alliance Specification for Display Command Set (DCS) is a good choice.

A full list and detail descriptions are composed in the document.
