Merge branch 'drm-next-4.17' of git://people.freedesktop.org/~agd5f/linux into drm-next
- Expose thermal thresholds through hwmon properly - Rework HDP flushing for rings and CPU - Improved dual-link DVI handling in DC - Lots of code clean up - Additional DC clean up - Allow scanout from system memory on CZ/BR/ST - Improved PASID/VM integration - Expose GPU voltage and power via hwmon - Initial wattman-like support - Initial power profiles for use-case optimized performance - Rework GPUVM TLB flushing - Rework IP offset handling for SOC15 asics - Add CRC support in DC - Fixes for mmhub powergating - Initial regamma/degamma/CTM support in DC - ttm cleanups and simplifications - ttm OOM avoidance fixes * 'drm-next-4.17' of git://people.freedesktop.org/~agd5f/linux: (348 commits) Revert "drm/radeon/pm: autoswitch power state when in balanced mode" drm/radeon: use drm_gem_private_object_init drm/amdgpu: use drm_gem_private_object_init drm/amdgpu: mitigate workaround for i915 drm/amdgpu: implement amdgpu_gem_map_(attach/detach) drm/amdgpu/powerplay/smu7: drop refresh rate checks for mclk switching drm/amdgpu/cgs: add refresh rate checking to non-DC display code drm/amd/powerplay/smu7: allow mclk switching with no displays drm/amd/powerplay/vega10: allow mclk switching with no displays drm/amd/powerplay: use PP_CAP macro for disable_mclk_switching_for_frame_lock drm/amd/powerplay: remove unused headers drm/amdgpu_gem: fix error handling path in amdgpu_gem_va_update_vm drm/amdgpu: update the PASID mapping only on demand drm/amdgpu: separate PASID mapping from VM flush v2 drm/amd/display: Fix increment when sampling OTF in DCE drm/amd/display: De PQ implementation drm/amd/display: Remove unused dm_pp_ interfaces drm/amd/display: Add logging for aux DPCD access drm/amd/display: Set vsc pack revision when DPCD revision is >= 1.2 drm/amd/display: provide an interface to query firmware version ...
