Yeah, you need to drop -C20 to get a bit saner "renames" in the patches =).

But otherwise, looks good.

One thing which is not strictly required, but I think should be added,
is cleaning up the omap-panel-data.h from the drm side. There are many
panels including the file, but not using it.

I don't think there's any sane way to split this series into different
subsystems. So I think we should merge this via drm tree.

Tony, can we get acks from you for the mach-omap2 patches? Do you think
there's anything there that could cause bigger conflicts?

 Tomi
