Pull drm fixes from Daniel Vetter: "Dave seems to collect an entire streak of things happening, so again me typing pull summary. Nothing nefarious here, most of the fixes are for new stuff or things users won't see. The amd-display patches are a bit different, and very much look like they should have at least some cc: stable tags. Might be amd is a bit too comfortable with their internal tree and not enough looking at upstream. Dave&me are looking into this, in case something needs rectified with process here. Also no intel fixes pull, but intel CI is general become rather good, still I guess expect a notch more for -rc3. Summary: amdgpu: - fixes for (new in 5.3) hw support (vega20, navi) - disable RAS - lots of display fixes all over (audio, DSC, dongle, clock mgr) ttm: - fix dma_free_attrs calls to appease dma debugging msm: - fixes for dma-api, locking debug and compiler splats core: - fix cmdline mode to not apply rotation if not specified (new in 5.3) - compiler warn fix" * tag 'drm-fixes-2019-07-26' of git://anongit.freedesktop.org/drm/drm: (46 commits) drm/amd/display: Set enabled to false at start of audio disable drm/amdgpu/smu: move fan rpm query into the asic specific code drm/amd/powerplay: custom peak clock freq for navi10 drm: silence variable 'conn' set but not used drm/msm: stop abusing dma_map/unmap for cache drm/msm/dpu: Correct dpu encoder spinlock initialization drm/msm: correct NULL pointer dereference in context_init drm/amd/display: handle active dongle port type is DP++ or DP case drm/amd/display: do not read link setting if edp not connected drm/amd/display: Increase size of audios array drm/amd/display: drop ASSERT() if eDP panel is not connected drm/amd/display: Only enable audio if speaker allocation exists drm/amd/display: Fix dc_create failure handling and 666 color depths drm/amd/display: allocate 4 ddc engines for RV2 drm/amd/display: put back front end initialization sequence drm/amd/display: Wait for flip to complete drm/amd/display: Change min_h_sync_width from 8 to 4 drm/amd/display: use encoder's engine id to find matched free audio device drm/amd/display: fix DMCU hang when going into Modern Standby drm/amd/display: Disable Audio on reinitialize hardware ...
