drm-misc-next for 5.11:

UAPI Changes:

Cross-subsystem Changes:

 * char/agp: Disable frontend without CONFIG_DRM_LEGACY
 * mm: Fix fput in mmap error path; Introduce vma_set_file() to change
   vma->vm_file

Core Changes:

 * dma-buf: Use sgtables in system heap; Move heap helpers to CMA-heap code;
   Skip sync for unmapped buffers; Alloc higher order pages is available;
   Respect num_fences when initializing shared fence list
 * doc: Improvements around DRM modes and SCALING_FILTER
 * Pass full state to connector atomic functions + callee updates
 * Cleanups
 * shmem: Map pages with caching by default; Cleanups
 * ttm: Fix DMA32 for global page pool
 * fbdev: Cleanups
 * fb-helper: Update framebuffer after userspace writes; Unmap console buffer
   during shutdown; Rework damage handling of shadow framebuffer

Driver Changes:

 * amdgpu: Multi-hop fixes, Clenaups
 * imx: Fix rotation for Vivante tiled formats; Support nearest-neighour
   skaling; Cleanups
 * mcde: Fix RGB formats; Support DPI output; Cleanups
 * meson: HDMI clock fixes
 * panel: Add driver and bindings for Innolux N125HCE-GN1
 * panel/s6e63m0: More backlight levels; Fix init; Cleanups
 * via: Clenunps
 * virtio: Use fence ID for handling fences; Cleanups
