Merge tag 'drm-next-2021-07-01' of git://anongit.freedesktop.org/drm/drm
Pull drm updates from Dave Airlie: "Highlights: - AMD enables two more GPUs, with resulting header files - i915 has started to move to TTM for discrete GPU and enable DG1 discrete GPU support (not by default yet) - new HyperV drm driver - vmwgfx adds arm64 support - TTM refactoring ongoing - 16bpc display support for AMD hw Otherwise it's just the usual insane amounts of work all over the place in lots of drivers and the core, as mostly summarised below: Core: - mark AGP ioctls as legacy - disable force probing for non-master clients - HDR metadata property helpers - HDMI infoframe signal colorimetry support - remove drm_device.pdev pointer - remove DRM_KMS_FB_HELPER config option - remove drm_pci_alloc/free - drm_err_*/drm_dbg_* helpers - use drm driver names for fbdev - leaked DMA handle fix - 16bpc fixed point format fourcc - add prefetching memcpy for WC - Documentation fixes aperture: - add aperture ownership helpers dp: - aux fixes - downstream 0 port handling - use extended base receiver capability DPCD - Rename DP_PSR_SELECTIVE_UPDATE to better mach eDP spec - mst: use khz as link rate during init - VCPI fixes for StarTech hub ttm: - provide tt_shrink file via debugfs - warn about freeing pinned BOs - fix swapping error handling - move page alignment into BO - cleanup ttm_agp_backend - add ttm_sys_manager - don't override vm_ops - ttm_bo_mmap removed - make ttm_resource base of all managers - remove VM_MIXEDMAP usage panel: - sysfs_emit support - simple: runtime PM support - simple: power up panel when reading EDID + caching bridge: - MHDP8546: HDCP support + DT bindings - MHDP8546: Register DP AUX channel with userspace - TI SN65DSI83 + SN65DSI84: add driver - Sil8620: Fix module dependencies - dw-hdmi: make CEC driver loading optional - Ti-sn65dsi86: refclk fixes, subdrivers, runtime pm - It66121: Add driver + DT bindings - Adv7511: Support I2S IEC958 encoding - Anx7625: fix power-on delay - Nwi-dsi: Modesetting fixes;
