Merge tag 'drm-intel-next-2015-03-27-merge' of git://anongit.freedesktop.org/drm-intel into drm-next
This backmerges 4.0-rc6 due to the recent fixes in rc5/6
- DP link rate refactoring from Ville
- byt/bsw rps tuning from Chris
- kerneldoc for the shrinker code
- more dynamic ppgtt pte work (Michel, Ben, ...)
- vlv dpll code refactoring to prep fro bxt (Imre)
- refactoring the sprite colorkey code (Ville)
- rotated ggtt view support from Tvrtko
- roll out struct drm_atomic_state to prep for atomic update (Ander)
