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 4.6 kernel. Overall the coolest thing here for me is the nouveau maxwell signed firmware support from NVidia, it's taken a long while to extract this from them. I also wish the ARM vendors just designed one set of display IP, ARM display block proliferation is definitely increasing. Core: - drm_event cleanups - Internal API cleanup making mode_fixup optional. - Apple GMUX vga switcheroo support. - DP AUX testing interface Panel: - Refactoring of DSI core for use over more transports. New driver: - ARM hdlcd driver i915: - FBC/PSR (framebuffer compression, panel self refresh) enabled by default. - Ongoing atomic display support work - Ongoing runtime PM work - Pixel clock limit checks - VBT DSI description support - GEM fixes - GuC firmware scheduler enhancements amdkfd: - Deferred probing fixes to avoid make file or link ordering. amdgpu/radeon: - ACP support for i2s audio support. - Command Submission/GPU scheduler/GPUVM optimisations - Initial GPU reset support for amdgpu vmwgfx: - Support for DX10 gen mipmaps - Pageflipping and other fixes. exynos: - Exynos5420 SoC support for FIMD - Exynos5422 SoC support for MIPI-DSI nouveau: - GM20x secure boot support - adds acceleration for Maxwell GPUs. - GM200 support - GM20B clock driver support - Power sensors work etnaviv: - Correctness fixes for GPU cache flushing - Better support for i.MX6 systems. imx-drm: - VBlank IRQ support - Fence support - OF endpoint support msm: - HDMI support for 8996 (snapdragon 820) - Adreno 430 support - Timestamp queries support virtio-gpu: - Fixes for Android support. rockchip: - Add support for Innosilicion HDMI rcar-du: - Support for 4 crtcs - R8A7795 support - RCar Gen 3 support omapdrm: - HDMI interlace output support - dma-buf import support - Refactoring to remove a lot of legacy code. tilcdc: - Rewrite of pageflipping code - dma-buf support - pinctrl support vc4: - HDMI modesetting bug fixes - Significant 3D performance improvement. fsl-dcu (FreeScale): - Lots of fixes tegra: - Two small fixes sti: - Atomic support for planes - Improved HDMI support" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (1063 commits) drm/amdgpu: release_pages requires linux/pagemap.h drm/sti: restore mode_fixup callback drm/amdgpu/gfx7: add MTYPE definition drm/amdgpu: removing BO_VAs shouldn't be interruptible drm/amd/powerplay: show uvd/vce power gate enablement for tonga. drm/amd/powerplay: show uvd/vce power gate info for fiji drm/amdgpu: use sched fence if possible drm/amdgpu: move ib.fence to job.fence drm/amdgpu: give a fence param to ib_free drm/amdgpu: include the right version of gmc header files for iceland drm/radeon: fix indentation. drm/amd/powerplay: add uvd/vce dpm enabling flag to fix the performance issue for CZ drm/amdgpu: switch back to 32bit hw fences v2 drm/amdgpu: remove amdgpu_fence_is_signaled drm/amdgpu: drop the extra fence range check v2 drm/amdgpu: signal fences directly in amdgpu_fence_process drm/amdgpu: cleanup amdgpu_fence_wait_empty v2 drm/amdgpu: keep all fences in an RCU protected array v2 drm/amdgpu: add number of hardware submissions to amdgpu_fence_driver_init_ring drm/amdgpu: RCU protected amd_sched_fence_release ...
