Merge tag 'drm-intel-next-2014-09-05' of git://anongit.freedesktop.org/drm-intel into drm-next

- final bits (again) for the rotation support (Sonika Jindal)
- support bl_power in the intel backlight (Jani)
- vdd handling improvements from Ville
- i830M fixes from Ville
- piles of prep work all over to make skl enabling just plug in (Damien, Sonika)
- rename DP training defines to reflect latest edp standards, this touches all
  drm drivers supporting DP (Sonika Jindal)
- cache edids during single detect cycle to avoid re-reading it for e.g. audio,
  from Chris
- move w/a for registers which are stored in the hw context to the context init
  code (Arun&Damien)
- edp panel power sequencer fixes, helps chv a lot (Ville)
- piles of other chv fixes all over
- much more paranoid pageflip handling with stall detection and better recovery
  from Chris
- small things all over, as usual
