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

- Support for a bunch of new panels
i915:
- VBT refactoring
- PLL computation cleanups

- 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
