Merge branch 'drm-intel-next' of git://anongit.freedesktop.org/drm-intel into drm-next

drm-intel-next-2015-01-30:
- chv rps improvements from Ville
- atomic state handling prep work from Ander
- execlist request tracking refactoring from Nick Hoath
- forcewake code consolidation from Chris&Mika
- fastboot plane config refactoring and skl support from Damien
- some more skl pm patches all over (Damien)
- refactor dsi code to use drm dsi helpers and drm_panel infrastructure (Jani)
- first cut at experimental atomic plane updates (Matt Roper)
- piles of smaller things all over, as usual
