Merge tag 'drm-misc-next-2021-07-16' of git://anongit.freedesktop.org/drm/drm-misc into drm-next
drm-misc-next for v5.15: UAPI Changes: Cross-subsystem Changes: - udmabuf: Add support for mapping hugepages - Add dma-buf stats to sysfs. - Assorted fixes to fbdev/omap2. - dma-buf: Document DMA_BUF_IOCTL_SYNC - Improve dma-buf non-dynamic exporter expectations better. - Add module parameters for dma-buf size and list limit. - Add HDMI codec support to vc4, to replace vc4's own codec. - Document dma-buf implicit fencing rules. - dma_resv_test_signaled test_all handling. Core Changes: - Extract i915's eDP backlight code into DRM helpers. - Assorted docbook updates. - Rework drm_dp_aux documentation. - Add support for the DP aux bus. - Shrink dma-fence-chain slightly. - Add alloc/free helpers for dma-fence-chain. - Assorted fixes to TTM., drm/of, bridge - drm_gem_plane_helper_prepare/cleanup_fb is now the default for gem drivers. - Small fix for scheduler completion. - Remove use of drm_device.irq_enabled. - Print the driver name to dmesg when registering framebuffer. - Export drm/gem's shadow plane handling, and use it in vkms. - Assorted small fixes. Driver Changes: - Add eDP backlight to nouveau. - Assorted fixes and cleanups to nouveau, panfrost, vmwgfx, anx7625, amdgpu, gma500, radeon, mgag200, vgem, vc4, vkms, omapdrm. - Add support for Samsung DB7430, Samsung ATNA33XC20, EDT ETMV570G2DHU, EDT ETM0350G0DH6, Innolux EJ030NA panels. - Fix some simple pannels missing bus_format and connector types. - Add mks-guest-stats instrumentation support to vmwgfx. - Merge i915-ttm topic branch. - Make s6e63m0 panel use Mipi-DBI helpers. - Add detect() supoprt for AST. - Use interrupts for hotplug on vc4. - vmwgfx is now moved to drm-misc-next, as sroland is no longer a maintainer for now. - vmwgfx now uses copies of vmware's internal device headers. - Slowly convert ti-sn65dsi83 over to atomic. - Rework amdgpu dma-resv handling. - Fix virtio fencing for planes. - Ensure amdgpu can always evict to SYSTEM. - Many drivers fixed for implicit fencing rules. - Set default prepare/cleanup fb for tiny, vram and simple helpers too. - Rework panfrost gpu reset and related serialization. - Update VKMS todo list. - Make bochs a tiny gpu driver, and use vram helper. - Use linux irq interfaces instead of drm_irq in some drivers. - Add support for Raspberry Pi Pico to GUD.
