Merge tag 'topic/drm-misc-2015-05-19' of git://anongit.freedesktop.org/drm-intel into drm-next
Scattering of random drm core patches. Bunch of atomic prep work too, but the final bits for blob properties, atomic modesets and lifting the experimental tag on the atomic ioctl are still blocked on Daniel Stone finalizing and testing the weston support for it. I hope that we can get it all ready for 4.2 though. * tag 'topic/drm-misc-2015-05-19' of git://anongit.freedesktop.org/drm-intel: (22 commits) drm/atomic: Allow drivers to subclass drm_atomic_state, v3 drm/atomic: remove duplicated assignment of old_plane_state drm/dp: Fix comment in DP helper drm/atomic: add drm_atomic_get_existing_*_state helpers drm/core: get rid of -Iinclude/drm drm/i915: get rid of -Iinclude/drm drm/atomic-helpers: Export drm_atomic_helper_update_legacy_modeset_state drm/atomic-helpers: Update vblank timestamping constants drm/sysfs: remove unnecessary connector type checks drm/sysfs: split DVI-I and TV-out attributes drm/sysfs: make optional attribute groups per connector type drm/sysfs: add a helper for extracting connector type from kobject drm/edid: Add CEA modes before inferred modes drm/prime: Allow internal imports without import_sg_table drm: Add reference counting to blob properties drm: Introduce blob_lock drm: Introduce helper for replacing blob properties drm: Don't leak path blob property when updating drm/atomic: Don't open-code CRTC state destroy drm/edid: Add DMT modes with ID > 0x50 ...
