Merge tag 'drm-for-v4.17' of git://people.freedesktop.org/~airlied/linux
Pull drm updates from Dave Airlie:
"Cannonlake and Vega12 support are probably the two major things. This
pull lacks nouveau, Ben had some unforseen leave and a few other
blockers so we'll see how things look or maybe leave it for this merge
window.
core:
- Device links to handle sound/gpu pm dependency
- Color encoding/range properties
- Plane clipping into plane check helper
- Backlight helpers
- DP TP4 + HBR3 helper support
amdgpu:
- Vega12 support
- Enable DC by default on all supported GPUs
- Powerplay restructuring and cleanup
- DC bandwidth calc updates
- DC backlight on pre-DCE11
- TTM backing store dropping support
- SR-IOV fixes
- Adding "wattman" like functionality
- DC crc support
- Improved DC dual-link handling
