Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "This is the main drm pull request for 4.5. I don't think I've missed anything too major, I'm mostly back at work now but I'll probably get some sleep in 5 years time. Summary: New drivers: - etnaviv: GPU driver for the 3D core on the Vivante core used in numerous ARM boards. Highlights: Core: - Atomic suspend/resume helpers - Move the headers to using userspace friendlier types. - Documentation updates - Lots of struct_mutex removal. - Bunch of DP MST fixes from AMD. Panel: - More DSI helpers - Support for some new basic panels i915: - Basic Kabylake support - DP link training and detect code refactoring - fbc/psr fixes - FIFO underrun fixes - SDE interrupt handling fixes - dma-buf/fence support in pageflip path. - GPU side for MST audio support radeon/amdgpu: - Drop UMS support - GPUVM/Scheduler optimisations - Initial Powerplay support for Tonga/Fiji/CZ/ST - ACP audio prerequisites nouveau: - GK20a instmem improvements - PCIE link speed change support msm: - DSI support for msm8960/apq8064 tegra: - Host1X support for Tegra210 SoC vc4: - 3D acceleration support armada: - Get rid of struct mutex tda998x: - Atomic modesetting support - TMDS clock limitations omapdrm: - Atomic modesetting support - improved TILER performance rockchip: - RK3036 VOP support - Atomic modesetting support - Synopsys DW MIPI DSI support exynos: - Runtime PM support - of_graph binding for DP panels - Cleanup of IPP code - Configurable plane support - Kernel panic fixes at release time" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (711 commits) drm/fb_cma_helper: Remove implicit call to disable_unused_functions drm/amdgpu: add missing irq.h include drm/vmwgfx: Fix a width / pitch mismatch on framebuffer updates drm/vmwgfx: Fix an incorrect lock check drm: nouveau: fix nouveau_debugfs_init prototype drm/nouveau/pci: fix check in nvkm_pcie_set_link drm/amdgpu: validate duplicates first drm/amdgpu: move VM page tables to the LRU end on CS v2 drm/ttm: add ttm_bo_move_to_lru_tail function v2 drm/ttm: fix adding foreign BOs to the swap LRU drm/ttm: fix adding foreign BOs to the LRU during init v2 drm/radeon: use kobj_to_dev() drm/amdgpu: use kobj_to_dev() drm/amdgpu/cz: force vce clocks when sclks are forced drm/amdgpu/cz: force uvd clocks when sclks are forced drm/amdgpu/cz: add code to enable forcing VCE clocks drm/amdgpu/cz: add code to enable forcing UVD clocks drm/amdgpu: fix lost sync_to if scheduler is enabled. drm/amd/powerplay: fix static checker warning for return meaningless value. drm/sysfs: use kobj_to_dev() ...
