I haven't done any bigger changes to my branch for some time now, and I'm just waiting to get some comments/acks for the bindings. So I suggest to also try out DSS DT for your board, based on the latest DSS DT branch: git://git.kernel.org/pub/scm/linux/kernel/git/tomba/linux.git work/dss-dt That way you have it ready and tested if DSS DT goes forward.

I'll send a display support patch as soon as DSS DT is in linux-next.

Full device tree support for omapdss is not yet accomplished. Until then, init display by legacy platform code.
