I'll give them a try tonight. I managed to get a hold of an adv7535 user manual, and there are some items that it appears NXP did in their downstream kernel that never got pushed upstream. Based on my review of some of the changes, some of the NXP changes seem reasonable to me. If/when I can get it working, I'll try to report back some of my findings and push driver changes to the adv7535 as I find them. adam
