Pull more drm updates from Dave Airlie: "Rob pointed out I missed his pull request for msm-next, it's been in next for a while outside of my tree so shouldn't cause any unexpected issues, it has some OCMEM support in drivers/soc that is acked by other maintainers as it's outside my tree. Otherwise it's a usual fixes pull, i915, amdgpu, the main ones, with some tegra, omap, mgag200 and one core fix. Summary: msm-next: - OCMEM support for a3xx and a4xx GPUs. - a510 support + display support core: - mst payload deletion fix i915: - uapi alignment fix - fix for power usage regression due to security fixes - change default preemption timeout to 640ms from 100ms - EHL voltage level display fixes - TGL DGL PHY fix - gvt - MI_ATOMIC cmd parser fix, CFL non-priv warning - CI spotted deadlock fix - EHL port D programming fix amdgpu: - VRAM lost fixes on BACO for CI/VI - navi14 DC fixes - misc SR-IOV, gfx10 fixes - XGMI fixes for arcturus - SRIOV fixes amdkfd: - KFD on ppc64le enabled - page table optimisations radeon: - fix for r1xx/2xx register checker. tegra: - displayport regression fixes - DMA API regression fixes mgag200: - fix devices that can't scanout except at 0 addr omap: - fix dma_addr refcounting" * tag 'drm-next-2019-12-06' of git://anongit.freedesktop.org/drm/drm: (100 commits) drm/dp_mst: Correct the bug in drm_dp_update_payload_part1() drm/omap: fix dma_addr refcounting drm/tegra: Run hub cleanup on ->remove() drm/tegra: sor: Make the +5V HDMI supply optional drm/tegra: Silence expected errors on IOMMU attach drm/tegra: vic: Export module device table drm/tegra: sor: Implement system suspend/resume drm/tegra: Use proper IOVA address for cursor image drm/tegra: gem: Remove premature import restrictions drm/tegra: gem: Properly pin imported buffers drm/tegra: hub: Remove bogus connection mutex check ia64: agp: Replace empty define with do while agp: Add bridge parameter documentation agp: remove unused variable num_segments agp: move AGPGART_MINOR to include/linux/miscdevice.h agp: remove unused variable size in agp_generic_create_gatt_table drm/dp_mst: Fix build on systems with STACKTRACE_SUPPORT=n drm/radeon: fix r1xx/r2xx register checker for POT textures drm/amdgpu: fix GFX10 missing CSIB set(v3) drm/amdgpu: should stop GFX ring in hw_fini ...
