Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm tree changes from Dave Airlie: "This is the main drm pull request, I have some overlap with sound and arm-soc, the sound patch is acked and may conflict based on -next reports but should be a trivial fixup, which I'll leave to you! Highlights: - new drivers: MSM driver from Rob Clark - non-drm: switcheroo and hdmi audio driver support for secondary GPU poweroff, so drivers can use runtime PM to poweroff the GPUs. This can save 5 or 6W on some optimus laptops. - drm core: combined GEM and TTM VMA manager per-filp mmap permission tracking initial rendernode support (via a runtime enable for now, until we get api stable), remove old proc support, lots of cleanups of legacy code hdmi vendor infoframes and 4k modes lots of gem/prime locking and races fixes async pageflip scaffolding drm bridge objects - i915: Haswell PC8+ support and eLLC support, HDMI 4K support, initial per-process VMA pieces, watermark reworks, convert to generic hdmi infoframes, encoder reworking, fastboot support, - radeon: CIK PM support, remove 3d blit code in favour of DMA engines, Berlin GPU support, HDMI audio fixes - nouveau: secondary GPU power down support for optimus laptops, lots of fixes, use MSI, VP3 engine support - exynos: runtime pm support for g2d, DT support, remove non-DT, - tda998x i2c driver: lots of fixes for sync issues - gma500: lots of cleanups - rcar: add LVDS support, fbdev emulation, - tegra: just minor fixes" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (684 commits) drm/exynos: Fix build error with exynos_drm_connector.c drm/exynos: Remove non-DT support in exynos_drm_fimd drm/exynos: Remove non-DT support in exynos_hdmi drm/exynos: Remove non-DT support in exynos_drm_g2d drm/exynos: Remove non-DT support in exynos_hdmiphy drm/exynos: Remove non-DT support in exynos_ddc drm/exynos: Make Exynos DRM drivers depend on OF drm/exynos: Consider fallback option to allocation fail drm/exynos: fimd: move platform data parsing to separate function drm/exynos: fimd: get signal polarities from device tree drm/exynos: fimd: replace struct fb_videomode with videomode drm/exynos: check a pixel format to a particular window layer drm/exynos: fix fimd pixel format setting drm/exynos: Add NULL pointer check drm/exynos: Remove redundant error messages drm/exynos: Add missing of.h header include drm/exynos: Remove redundant NULL check in exynos_drm_buf drm/exynos: add device tree support for rotator drm/exynos: Add missing includes drm/exynos: add runtime pm interfaces to g2d driver ...
