Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull DRM updates from Dave Airlie:
"This is the one and only next pull for 3.8, we had a regression we
found last week, so I was waiting for that to resolve itself, and I
ended up with some Intel fixes on top as well.
Highlights:
- new driver: nvidia tegra 20/30/hdmi support
- radeon: add support for previously unused DMA engines, more HDMI
regs, eviction speeds ups and fixes
- i915: HSW support enable, agp removal on GEN6, seqno wrapping
- exynos: IPP subsystem support (image post proc), HDMI
- nouveau: display class reworking, nv20->40 z compression
- ttm: start of locking fixes, rcu usage for lookups,
- core: documentation updates, docbook integration, monotonic clock
usage, move from connector to object properties"
