Merge branch 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux into drm-next
Fixes for 4.12. This is a bit bigger than usual since it's 3 weeks worth of fixes and most of these changes are for vega10 which is new for 4.12 and still in a fair amount of flux. It looks like you missed my last pull request, so those patches are included here as well. Highlights: - Lots of vega10 fixes - Fix interruptable wait mixup - Fan control method fixes - Misc display fixes for radeon and amdgpu - Misc bug fixes * 'drm-next-4.12' of git://people.freedesktop.org/~agd5f/linux: (132 commits) drm/amd/powerplay: refine pwm1_enable callback functions for CI. drm/amd/powerplay: refine pwm1_enable callback functions for vi. drm/amd/powerplay: refine pwm1_enable callback functions for Vega10. drm/amdgpu: refine amdgpu pwm1_enable sysfs interface. drm/amdgpu: add amd fan ctrl mode enums. drm/amd/powerplay: add more smu message on Vega10. drm/amdgpu: fix dependency issue drm/amd: fix init order of sched job drm/amdgpu: add some additional vega10 pci ids drm/amdgpu/soc15: use atomfirmware for setting bios scratch for reset drm/amdgpu/atomfirmware: add function to update engine hang status drm/radeon: only warn once in radeon_ttm_bo_destroy if va list not empty drm/amdgpu: fix mutex list null pointer reference drm/amd/powerplay: fix bug sclk/mclk level can't be set on vega10. drm/amd/powerplay: Setup sw CTF to allow graceful exit when temperature exceeds maximum. drm/amd/powerplay: delete dead code in powerplay. drm/amdgpu: Use less generic enum definitions drm/amdgpu/gfx9: derive tile pipes from golden settings drm/amdgpu/gfx: drop max_gs_waves_per_vgt drm/amd/powerplay: disable engine spread spectrum feature on Vega10. ...
