[PATCH 00/10] vc4: scaling and YUV overlays for 4.6

[Eric Anholt <eric@anholt.net>]

Here's the major series I have currently for 4.6: Overlay plane
support.  There's definitely more work to be done here, on better
filter kernels at various sizes, choosing our scaling modes better,
and being more aggressive on LBM allocation (right now I think we're
barely allocating for YUV 1:1 at 1920x1080, but it could do more than
that).  However, I think this is a good base to build from and may
unblock people trying to start building software stacks on the open
driver.

Eric Anholt (10):
  drm/vc4: Improve comments on vc4_plane_state members.
  drm/vc4: Add missing __iomem annotation to hw_dlist.
  drm/vc4: Move the plane clipping/scaling setup to a separate function.
  drm/vc4: Add a proper short-circut path for legacy cursor updates.
  drm/vc4: Make the CRTCs cooperate on allocating display lists.
  drm/vc4: Add more display planes to each CRTC.
  drm/vc4: Fix which value is being used for source image size.
  drm/vc4: Add support for scaling of display planes.
  drm/vc4: Add support a few more RGB display plane formats.
  drm/vc4: Add support for YUV planes.
