Merge tag 'drm-next-2023-11-07' of git://anongit.freedesktop.org/drm/drm
Pull more drm updates from Dave Airlie: "Geert pointed out I missed the renesas reworks in my main pull, so this pull contains the renesas next work for atomic conversion and DT support. It also contains a bunch of amdgpu and some small ssd13xx fixes. renesas: - atomic conversion - DT support ssd13xx: - dt binding fix for ssd132x - Initialize ssd130x crtc_state to NULL. amdgpu: - Fix RAS support check - RAS fixes - MES fixes - SMU13 fixes - Contiguous memory allocation fix - BACO fixes - GPU reset fixes - Min power limit fixes - GFX11 fixes - USB4/TB hotplug fixes - ARM regression fix - GFX9.4.3 fixes - KASAN/KCSAN stack size check fixes - SR-IOV fixes - SMU14 fixes - PSP13 fixes - Display blend fixes - Flexible array size fixes amdkfd: - GPUVM fix radeon: - Flexible array size fixes" * tag 'drm-next-2023-11-07' of git://anongit.freedesktop.org/drm/drm: (83 commits) drm/amd/display: Enable fast update on blendTF change drm/amd/display: Fix blend LUT programming drm/amd/display: Program plane color setting correctly drm/amdgpu: Query and report boot status drm/amdgpu: Add psp v13 function to query boot status drm/amd/swsmu: remove fw version check in sw_init. drm/amd/swsmu: update smu v14_0_0 driver if and metrics table drm/amdgpu: Add C2PMSG_109/126 reg field shift/masks drm/amdgpu: Optimize the asic type fix code drm/amdgpu: fix GRBM read timeout when do mes_self_test drm/amdgpu: check recovery status of xgmi hive in ras_reset_error_count drm/amd/pm: only check sriov vf flag once when creating hwmon sysfs drm/amdgpu: Attach eviction fence on alloc drm/amdkfd: Improve amdgpu_vm_handle_moved drm/amd/display: Increase frame warning limit with KASAN or KCSAN in dml2 drm/amd/display: Avoid NULL dereference of timing generator drm/amdkfd: Update cache info for GFX 9.4.3 drm/amdkfd: Populate cache info for GFX 9.4.3 drm/amdgpu: don't put MQDs in VRAM on ARM | ARM64 drm/amdgpu/smu13: drop compute workload workaround ...
