Merge drm updates from Dave Airlie: "This is the main drm pull request for 4.8. I'm down with a cold at the moment so hopefully this isn't in too bad a state, I finished pulling stuff last week mostly (nouveau fixes just went in today), so only this message should be influenced by illness. Apologies to anyone who's major feature I missed :-) Core: Lockless GEM BO freeing Non-blocking atomic work Documentation changes (rst/sphinx) Prep for new fencing changes Simple display helpers Master/auth changes Register/unregister rework Loads of trivial patches/fixes. New stuff: ARM Mali display driver (not the 3D chip) sii902x RGB->HDMI bridge Panel: Support for new panels Improved backlight support Bridge: Convert ADV7511 to bridge driver ADV7533 support TC358767 (DSI/DPI to eDP) encoder chip support i915: BXT support enabled by default GVT-g infrastructure GuC command submission and fixes BXT workarounds SKL/BKL workarounds Demidlayering device registration Thundering herd fixes Missing pci ids Atomic updates amdgpu/radeon: ATPX improvements for better dGPU power control on PX systems New power features for CZ/BR/ST Pipelined BO moves and evictions in TTM GPU scheduler improvements GPU reset improvements Overclocking on dGPUs with amdgpu Polaris powermanagement enabled nouveau: GK20A/GM20B volt and clock improvements. Initial support for GP100/GP104 GPUs, GP104 will not yet support acceleration due to NVIDIA having not released firmware for them as of yet. exynos: Exynos5433 SoC with IOMMU support. vc4: Shader validation for branching imx-drm: Atomic mode setting conversion Reworked DMFC FIFO allocation External bridge support analogix-dp: RK3399 eDP support Lots of fixes. rockchip: Lots of small fixes. msm: DT bindings cleanups Shrinker and madvise support ASoC HDMI codec support tegra: Host1x driver cleanups SOR reworking for DP support Runtime PM support omapdrm: PLL enhancements Header refactoring Gamma table support arcgpu: Simulator support virtio-gpu: Atomic modesetting fixes. rcar-du: Misc fixes. mediatek: MT8173 HDMI support sti: ASOC HDMI codec support Minor fixes fsl-dcu: Suspend/resume support Bridge support amdkfd: Minor fixes. etnaviv: Enable GPU clock gating hisilicon: Vblank and other fixes" * tag 'drm-for-v4.8' of git://people.freedesktop.org/~airlied/linux: (1575 commits) drm/nouveau/gr/nv3x: fix instobj write offsets in gr setup drm/nouveau/acpi: fix lockup with PCIe runtime PM drm/nouveau/acpi: check for function 0x1B before using it drm/nouveau/acpi: return supported DSM functions drm/nouveau/acpi: ensure matching ACPI handle and supported functions drm/nouveau/fbcon: fix font width not divisible by 8 drm/amd/powerplay: remove enable_clock_power_gatings_tasks from initialize and resume events drm/amd/powerplay: move clockgating to after ungating power in pp for uvd/vce drm/amdgpu: add query device id and revision id into system info entry at CGS drm/amdgpu: add new definition in bif header drm/amd/powerplay: rename smum header guards drm/amdgpu: enable UVD context buffer for older HW drm/amdgpu: fix default UVD context size drm/amdgpu: fix incorrect type of info_id drm/amdgpu: make amdgpu_cgs_call_acpi_method as static drm/amdgpu: comment out unused defaults_staturn_pro static const structure to fix the build drm/amdgpu: enable UVD VM only on polaris drm/amdgpu: increase timeout of IB test drm/amdgpu: add destroy session when generate VCE destroy msg. drm/amd: fix deadlock of job_list_lock V2 ...
