Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie: "Here's the main drm pull request for 4.7, it's been a busy one, and I've been a bit more distracted in real life this merge window. Lots more ARM drivers, not sure if it'll ever end. I think I've at least one more coming the next merge window. But changes are all over the place, support for AMD Polaris GPUs is in here, some missing GM108 support for nouveau (found in some Lenovos), a bunch of MST and skylake fixes. I've also noticed a few fixes from Arnd in my inbox, that I'll try and get in asap, but I didn't think they should hold this up. New drivers: - Hisilicon kirin display driver - Mediatek MT8173 display driver - ARC PGU - bitstreamer on Synopsys ARC SDP boards - Allwinner A13 initial RGB output driver - Analogix driver for DisplayPort IP found in exynos and rockchip DRM Core: - UAPI headers fixes and C++ safety - DRM connector reference counting - DisplayID mode parsing for Dell 5K monitors - Removal of struct_mutex from drivers - Connector registration cleanups - MST robustness fixes - MAINTAINERS updates - Lockless GEM object freeing - Generic fbdev deferred IO support panel: - Support for a bunch of new panels i915: - VBT refactoring - PLL computation cleanups - DSI support for BXT - Color manager support - More atomic patches - GEM improvements - GuC fw loading fixes - DP detection fixes - SKL GPU hang fixes - Lots of BXT fixes radeon/amdgpu: - Initial Polaris support - GPUVM/Scheduler/Clock/Power improvements - ASYNC pageflip support - New mesa feature support nouveau: - GM108 support - Power sensor support improvements - GR init + ucode fixes. - Use GPU provided topology information vmwgfx: - Add host messaging support gma500: - Some cleanups and fixes atmel: - Bridge support - Async atomic commit support fsl-dcu: - Timing controller for LCD support - Pixel clock polarity support rcar-du: - Misc fixes exynos: - Pipeline clock support - Exynoss4533 SoC support - HW trigger mode support - export HDMI_PHY clock - DECON5433 fixes - Use generic prime functions - use DMA mapping APIs rockchip: - Lots of little fixes vc4: - Render node support - Gamma ramp support - DPI output support msm: - Mostly cleanups and fixes - Conversion to generic struct fence etnaviv: - Fix for prime buffer handling - Allow hangcheck to be coalesced with other wakeups tegra: - Gamme table size fix" * 'drm-next' of git://people.freedesktop.org/~airlied/linux: (1050 commits) drm/edid: add displayid detailed 1 timings to the modelist.
