Pull more drm updates from Daniel Vetter:
"UAPI Changes:
- Only enable char/agp uapi when CONFIG_DRM_LEGACY is set
Cross-subsystem Changes:
- vma_set_file helper to make vma->vm_file changing less brittle,
acked by Andrew
Core Changes:
- dma-buf heaps improvements
- pass full atomic modeset state to driver callbacks
- shmem helpers: cached bo by default
- cleanups for fbdev, fb-helpers
- better docs for drm modes and SCALING_FITLER uapi
- ttm: fix dma32 page pool regression
Driver Changes:
- multi-hop regression fixes for amdgpu, radeon, nouveau
- lots of small amdgpu hw enabling fixes (display, pm, ...)
- fixes for imx, mcde, meson, some panels, virtio, qxl, i915, all
fairly minor
- some cleanups for legacy drm/fbdev drivers"
