Merge tag 'topic/drm-misc-2016-07-14' of git://anongit.freedesktop.org/drm-intel into drm-next 

I recovered dri-devel backlog from my vacation, more misc stuff:
- of_put_node fixes from Peter Chen (not all yet)
- more patches from Gustavo to use kms-native drm_crtc_vblank_* funcs
- docs sphinxification from Lukas Wunner
- bunch of fixes all over from Dan Carpenter
- more follow up work from Chris register/unregister rework in various
  places
- vgem dma-buf export (for writing testcases)
- small things all over from tons of different people

The lastclose method should restore CRTC and plane properties to default

over.

	---help---

	  This option enables the fence framework synchronization to export

	  sync_files to userspace that can represent one or more fences.

	  The Sync File Framework adds explicit syncronization via

	  userspace. It enables send/receive 'struct fence' objects to/from

	  userspace via Sync File fds for synchronization between drivers via

	  userspace components. It has been ported from Android.



	  The first and main user for this is graphics in which a fence is

	  associated with a buffer. When a job is submitted to the GPU a fence

	  is attached to the buffer and is transferred via userspace, using Sync

	  Files fds, to the DRM driver for example. More details at

	  Documentation/sync_file.txt.
