Ok, I think this is a good foundation to build on and later on add more
pieces to fix suspend/resume and similar.

But we also need to discuss how to merge this. My proposal is that I do a
special topic branch with just the patches in this series and then pull
that into drm-intel-next and send a pull request for it to Takashi for
sound-next, too. That way we don't have any depencies between drm and
sound for the 3.20 merge window.

Testing by intel QA is also solved this way since sound-next is already
pulled into drm-intel-nightly. And both gfx and sound QA use that branch.

Takashi/Dave, does this sound good?

Thanks, Daniel
