I suppose the rest of the patch is OK since it works for you.

I don't know any of this code. It would be nice to know what some of those pm2_RD(par, SOME_REG) mean so that I could sort of understand what it is doing, but don't go spending time on it just for me. It's not worth doing that IMO.

Thank you Randy. I have sent another revision. I am also curious about those registers -- but it is hard to accurately figure it out without datasheet -- my speculation is that it calls the device to do some sort of frame buffer synchronizations here Thanks, - Tong
