Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "I Was Almost Tempted To Capitalise Every Word, but then I decided I couldn't read it myself! I've also got one pull request for the sti driver outstanding. It relied on a commit in Greg's tree and I didn't find out in time, that commit is in your tree now so I might send that along once this is merged. I also had the accidental misfortune to have access to a Skylake on my desk for a few days, and I've had to encourage Intel to try harder, which seems to be happening now. Here is the main drm-next pull request for 4.4. Highlights: New driver: vc4 driver for the Rasberry Pi VPU. (From Eric Anholt at Broadcom.) Core: Atomic fbdev support Atomic helpers for runtime pm dp/aux i2c STATUS_UPDATE handling struct_mutex usage cleanups. Generic of probing support. Documentation: Kerneldoc for VGA switcheroo code. Rename to gpu instead of drm to reflect scope. i915: Skylake GuC firmware fixes HPD A support VBT backlight fallbacks Fastboot by default for some systems FBC work BXT/SKL workarounds Skylake deeper sleep state fixes amdgpu: Enable GPU scheduler by default New atombios opcodes GPUVM debugging options Stoney support. Fencing cleanups. radeon: More efficient CS checking nouveau: gk20a instance memory handling improvements. Improved PGOB detection and GK107 support Kepler GDDR5 PLL statbility improvement G8x/GT2xx reclock improvements new userspace API compatiblity fixes. virtio-gpu: Add 3D support - qemu 2.5 has it merged for it's gtk backend. msm: Initial msm88896 (snapdragon 8200) exynos: HDMI cleanups Enable mixer driver byt default Add DECON-TV support vmwgfx: Move to using memremap + fixes. rcar-du: Add support for R8A7793/4 DU armada: Remove support for non-component mode Improved plane handling Power savings while in DPMS off. tda998x: Remove unused slave encoder support Use more HDMI helpers Fix EDID read handling dwhdmi: Interlace video mode support for ipu-v3/dw_hdmi Hotplug state fixes Audio driver integration imx: More color formats support. tegra: Minor fixes/improvements" [ Merge fixup: remove unused variable 'dev' that had all uses removed in commit 4e270f088011: "drm/gem: Drop struct_mutex requirement from drm_gem_mmap_obj" ] * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (764 commits) drm/vmwgfx: Relax irq locking somewhat drm/vmwgfx: Properly flush cursor updates and page-flips drm/i915/skl: disable display side power well support for now drm/i915: Extend DSL readout fix to BDW and SKL. drm/i915: Do graphics device reset under forcewake drm/i915: Skip fence installation for objects with rotated views (v4) vga_switcheroo: Drop client power state VGA_SWITCHEROO_INIT drm/amdgpu: group together common fence implementation drm/amdgpu: remove AMDGPU_FENCE_OWNER_MOVE drm/amdgpu: remove now unused fence functions drm/amdgpu: fix fence fallback check drm/amdgpu: fix stoping the scheduler timeout drm/amdgpu: cleanup on error in amdgpu_cs_ioctl() drm/i915: Fix locking around GuC firmware load drm/amdgpu: update Fiji's Golden setting drm/amdgpu: update Fiji's rev id drm/amdgpu: extract common code in vi_common_early_init drm/amd/scheduler: don't oops on failure to load drm/amdgpu: don't oops on failure to load (v2) drm/amdgpu: don't VT switch on suspend ...
