I understand that there's something wrong with the code, but it turned out not to be easy to debug. Yes, it will have to be debugged some day, but it happens with old code, too, so it is actually orthogonal to device tree. > Beside my comments and the ones from Javier, it looks good. > If you can repost ASAP, I'll take it right after. > It will be the first one in the list. Thanks, here you go. Pavel --- This adds device tree with neccessary support to boot with functional video (on both emulator and real N900 device).

I re-enabled parts that can be enabled on 3.10, and tested it on that kernel. >From v2: spelling, improved comments.
