Medium, there's other stuff that I can be getting on with.
I've been looking through the H2 manual but there's nothing specifically
saying the DU0 and DU2 planes should be linked. I know DU0_0 and DU0_1
are basically linked.
We are using the Lager board as following:
We have DU0 outputting LVDS to the ADV7511 to provide DVI
DU2 is connected to the DPAD0 to the VGA
DU0 is configured for 1920x1080-60, 32bpp
DU2 is configured for 800x600-60, 32bpp
DU2 has been verified as outputting 800x600-60 display timings.
