Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"Highlights:
- drm:
Generic display port aux features, primary plane support, drm
master management fixes, logging cleanups, enforced locking checks
(instead of docs), documentation improvements, minor number
handling cleanup, pseudofs for shared inodes.
- ttm:
add ability to allocate from both ends
- i915:
broadwell features, power domain and runtime pm, per-process
address space infrastructure (not enabled)
- msm:
power management, hdmi audio support
- nouveau:
ongoing GPU fault recovery, initial maxwell support, random fixes
- exynos:
refactored driver to clean up a lot of abstraction, DP support
moved into drm, LVDS bridge support added, parallel panel support
- gma500:
SGX MMU support, SGX irq handling, asle irq work fixes
- radeon:
video engine bringup, ring handling fixes, use dp aux helpers
- vmwgfx:
add rendernode support"
