imx-drm: screen flickering

[Christian Gmeiner]

Hi all.

>From time to time it happens that my LVDS display is flickering (look
at scroll bar in the video).

I really want to find the root cause of it, but I do not know where to
start. I can trigger this
sometimes after xscreensever "blanks" the screen and the screensafer
gets disabled
via user input.

Any hints?
