Thanks a lot for the help. So far, I'm not playing with
suspend/resume, so wkup/core split should not be issue (right?).
How does it work with the devices? AFAICT omap4 groups it logically,
but that's just for easy reading, no?
I tried this, but no luck, mux is not initialized correctly, so code
in board-rx51-video fails, and later fbcon crashes.
Any ideas?
