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" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (590 commits) drm/exynos: add gsc ipp driver drm/exynos: add rotator ipp driver drm/exynos: add fimc ipp driver drm/exynos: add iommu support for ipp drm/exynos: add ipp subsystem drm/exynos: support device tree for fimd radeon: fix regression with eviction since evict caching changes drm/radeon: add more pedantic checks in the CP DMA checker drm/radeon: bump version for CS ioctl support for async DMA drm/radeon: enable the async DMA rings in the CS ioctl drm/radeon: add VM CS parser support for async DMA on cayman/TN/SI drm/radeon/kms: add evergreen/cayman CS parser for async DMA (v2) drm/radeon/kms: add 6xx/7xx CS parser for async DMA (v2) drm/radeon: fix htile buffer size computation for command stream checker drm/radeon: fix fence locking in the pageflip callback drm/radeon: make indirect register access concurrency-safe drm/radeon: add W|RREG32_IDX for MM_INDEX|DATA based mmio accesss drm/exynos: support extended screen coordinate of fimd drm/exynos: fix x, y coordinates for right bottom pixel drm/exynos: fix fb offset calculation for plane ...
