Merge branch 'for-next' of ssh://people.freedesktop.org/~seanpaul/dogwood into drm-next

I've included some improvements to PSR from myself, as well as a great
series from Tomasz to clean up and tighten up vblank/flip handling.

The last patch is one from Tomeu that has been floating around for a
while, and since rockchip is one of the beneficiaries, I figured this
would be a good place to pick it up.
