Merge tag 'drm-fixes-2020-08-28' of git://anongit.freedesktop.org/drm/drm
Pull drm fixes from Dave Airlie: "As expected a bit of an rc3 uptick, amdgpu and msm are the main ones, one msm patch was from the merge window, but had dependencies and we dropped it until the other tree had landed. Otherwise it's a couple of fixes for core, and etnaviv, and single i915, exynos, omap fixes. I'm still tracking the Sandybridge gpu relocations issue, if we don't see much movement I might just queue up the reverts. I'll talk to Daniel next week once he's back from holidays. core: - Take modeset bkl for legacy drivers dp_mst: - Allow null crtc in dp_mst i915: - Fix command parser desc matching with masks amdgpu: - Misc display fixes - Backlight fixes - MPO fix for DCN1 - Fixes for Sienna Cichlid - Fixes for Navy Flounder - Vega SW CTF fixes - SMU fix for Raven - Fix a possible overflow in INFO ioctl - Gfx10 clockgating fix msm: - opp/bw scaling patch followup - frequency restoring fux - vblank in atomic commit fix - dpu modesetting fixes - fencing fix etnaviv: - scheduler interaction fix - gpu init regression fix exynos: - Just drop __iommu annotation to fix sparse warning omap: - locking state fix" * tag 'drm-fixes-2020-08-28' of git://anongit.freedesktop.org/drm/drm: (41 commits) drm/amd/display: Fix memleak in amdgpu_dm_mode_config_init drm/amdgpu: disable runtime pm for navy_flounder drm/amd/display: Retry AUX write when fail occurs drm/amdgpu: Fix buffer overflow in INFO ioctl drm/amd/powerplay: Fix hardmins not being sent to SMU for RV drm/amdgpu: use MODE1 reset for navy_flounder by default drm/amd/pm: correct the thermal alert temperature limit settings drm/amdgpu: add asd fw check before loading asd drm/amd/display: Keep current gain when ABM disable immediately drm/amd/display: Fix passive dongle mistaken as active dongle in EDID emulation drm/amd/display: Revert HDCP disable sequence change drm/amd/display: Send DISPLAY_OFF after power down on boot drm/amdgpu/gfx10: refine mgcg setting drm/amd/pm: correct Vega20 swctf limit setting drm/amd/pm: correct Vega12 swctf limit setting drm/amd/pm: correct Vega10 swctf limit setting drm/amd/pm: set VCN pg per instances drm/amd/pm: enable run_btc callback for sienna_cichlid drivers: gpu: amd: Initialize amdgpu_dm_backlight_caps object to 0 in amdgpu_dm_update_backlight_caps drm/amd/display: Reject overlay plane configurations in multi-display scenarios ...
