hi all:

 We use I.mx8m design reference board .and use tc358775 convert mipi-dsi to lvds signal. 

 I use linux 4.9.88 and android 8.1.0 for test.

 do the following test

 a). use lcdif to display single on linux system and screen resolution 1920x1080   it display well.

 b). use lcdif and dcss dual  display on linux system. the screen which resolution is 1920x1080 will flicker if the system play 4K video.

 c)   use lcdif and dcss dual display on linux system. the screen which resolution is 1280x800 will work well,no matter the system work.

d)  use dcss to display single on android system, the screen resolution 1920x1080 can`t work and screen blurred

 f)   use dcss to display single on android system ,the screen resolution 1280x800 work well

 e)  use lcdif to display single the on android system .the surfacefinger  will error and system halt
