Merge tag 'drm-next-2020-02-07' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie:
"Just some fixes for this merge window: the tegra changes fix some
regressions in the merge, nouveau has a few modesetting fixes.
The amdgpu fixes are bit bigger, but they contain a couple of weeks of
fixes, and don't seem to contain anything that isn't really a fix.
Summary:
tegra:
- merge window regression fixes
nouveau:
- couple of volta/turing modesetting fixes
amdgpu:
- EDC fixes for Arcturus
- GDDR6 memory training fixe
- Fix for reading gfx clockgating registers while in GFXOFF state
- i2c freq fixes
- Misc display fixes
- TLB invalidation fix when using semaphores
- VCN 2.5 instancing fixes
- Switch raven1 gfxoff to a blacklist
- Coreboot workaround for KV/KB
- Root cause dongle fixes for display and revert workaround
- Enable GPU reset for renoir and navi
- Navi overclocking fixes
- Fix up confusing warnings in display clock validation on raven
amdkfd:
- SDMA fix
radeon:
- Misc LUT fixes"
