That's my first submission of a DRM driver and I'm wondering
which tree/branch should I use as a reference to rebase my
patches and send you a pull request?

Especially given there's a prerequisite which is still only in
linux-next:+AKA-http://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id+AD0-54d2c2da0946368b96b63e6daed7920f3
