Merge tag 'drm-intel-next-2016-07-11' of git://anongit.freedesktop.org/drm-intel into drm-next 

- select igt testing depencies for CONFIG_DRM_I915_DEBUG (Chris)
- track outputs in crtc state and clean up all our ad-hoc connector/encoder
  walking in modest code (Ville)
- demidlayer drm_device/drm_i915_private (Chris Wilson)
- thundering herd fix from Chris Wilson, with lots of help from Tvrtko Ursulin
- piles of assorted clean and fallout from the thundering herd fix
- documentation and more tuning for waitboosting (Chris)
- pooled EU support on bxt (Arun Siluvery)
- bxt support is no longer considered prelimary!
- ring/engine vfunc cleanup from Tvrtko
- introduce intel_wait_for_register helper (Chris)
- opregion updates (Jani Nukla)
- tuning and fixes for wait_for macros (Tvrkto&Imre)
- more kabylake pci ids (Rodrigo)
- pps cleanup and fixes for bxt (Imre)
- move sink crc support over to atomic state (Maarten)
- fix up async fbdev init ordering (Chris)
- fbc fixes from Paulo and Chris
