Thank you very much for the patch. With the new kernel I don't see the
bouncing on HDMI problem.
I am using HDMI to DVI cable to test 1080 as I don't have 1080 HDMI monitor.
With the new kernel Linux does not drive the DVI monitor at all. I switched
to 720 HDMI monitor and now there is output signal but I get horizontal
scrolling lines across the screen!
I don't see this problem with u-boot or Freescale kernel.
Have you seen this problem before?
