Merge tag 'drm-for-v4.16' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"This seems to have been a comparatively quieter merge window, I assume
due to holidays etc. The "biggest" change is AMD header cleanups, which
merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
with the etnaviv driver wanting to reuse the code, hopefully other drivers
can go in the same direction.
Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
elsewhere.
Core:
- Add .last_close and .output_poll_changed helpers to reduce driver footprints
- Fix plane clipping
- Improved debug printing support
- Add panel orientation property
- Update edid derived properties at edid setting
- Reduction in fbdev driver footprint
- Move amdgpu scheduler into core for other drivers to use.
i915:
- Selftest and IGT improvements
- Fast boot prep work on IPS, pipe config
- HW workarounds for Cannonlake, Geminilake
- Cannonlake clock and HDMI2.0 fixes
- GPU cache invalidation and context switch improvements
- Display planes cleanup
- New PMU interface for perf queries
- New firmware support for KBL/SKL
- Geminilake HW workaround for perforamce
- Coffeelake stolen memory improvements
- GPU reset robustness work
- Cannonlake horizontal plane flipping
- GVT work
amdgpu/radeon:
- RV and Vega header file cleanups (lots of lines gone!)
- TTM operation context support
- 48-bit GPUVM support for Vega/RV
- ECC support for Vega
- Resizeable BAR support
- Multi-display sync support
- Enable swapout for reserved BOs during allocation
- S3 fixes on Raven
- GPU reset cleanup and fixes
- 2+1 level GPU page table
amdkfd:
- GFX7/8 SDMA user queues support
- Hardware scheduling for multiple processes
- dGPU prep work
rcar:
- Added R8A7743/5 support
- System suspend/resume support
sun4i:
- Multi-plane support for YUV formats
- A83T and LVDS support
msm:
- Devfreq support for GPU
tegra:
- Prep work for adding Tegra186 support
- Tegra186 HDMI support
- HDMI2.0 and zpos support by using generic helpers
tilcdc:
- Misc fixes
omapdrm:
- Support memory bandwidth limits
- DSI command mode panel cleanups
- DMM error handling
exynos:
- drop the old IPP subdriver.
etnaviv:
- Occlusion query fixes
- Job handling fixes
- Prep work for hooking in gpu scheduler
armada:
- Move closer to atomic modesetting
- Allow disabling primary plane if overlay is full screen
imx:
- Format modifier support
- Add tile prefetch to PRE
- Runtime PM support for PRG
ast:
- fix LUT loading"
