Merge tag 'amd-drm-next-5.12-2021-01-20' of https://gitlab.freedesktop.org/agd5f/linux into drm-next
amd-drm-next-5.12-2021-01-20: amdgpu: - Fix non-x86 build - W=1 fixes from Lee Jones - Enable GPU reset on Navy Flounder - Kernel doc fixes - SMU workload profile fixes for APUs - Display updates - SR-IOV fixes - Vangogh SMU feature enablment and bug fixes - GPU reset support for Vangogh - Misc cleanups Conflicts: drivers/gpu/drm/amd/display/dc/dcn10/dcn10_mpc.c Resolve the conflict by picking the initialization value from amd from f03e80d2e82c ("drm/amd/display: Initialize stack variable") over the one Linus picked in 61d791365b72 ("drm/amd/display: avoid uninitialized variable warning"). It shouldn't matter.
