Merge tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel into drm-next 

As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
  some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
  vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
  implementations we have (we really only need that for truly dynamic
  cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
  intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over

* tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel: (47 commits)

* This is useful in atomic check callbacks, when drivers need to peek at, but

*
* Note that this function is in general unsafe since it doesn't check for the
* required locking for access state structures. Drivers must ensure that it is
* safe to access the returned state structure through other means. One common
* example is when planes are fixed to a single CRTC, and the driver knows that
* the CRTC lock is held already. In that case holding the CRTC lock gives a
* read-lock on all planes connected to that CRTC. But if planes can be
* reassigned things get more tricky. In that case it's better to use
* drm_atomic_get_plane_state and wire up full error handling.
