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) drm/dsi: Implement set tear scanline drm/fb_cma_helper: Implement fb_mmap callback drm/qxl: Remove useless drm_fb_get_bpp_depth() call drm/ast: Remove useless drm_fb_get_bpp_depth() call drm/atomic: Fix remaining places where !funcs->best_encoder is valid drm/core: Change declaration for gamma_set.
