-Subject: [PATCH] drm/vc4: Add support for YUV planes.
-
-This supports 420 and 422 subsampling with 2 or 3 planes, tested with
-modetest. It doesn't set up chroma subsampling position (which it
-appears KMS doesn't deal with yet).
-
-The LBM memory is overallocated in many cases, but apparently the docs
-aren't quite correct and I'll probably need to look at the hardware
-source to really figure it out.
-
-Signed-off-by: Eric Anholt <eric@anholt.net>
-(cherry picked from commit fc04023fafecf19ebd09278d8d67dc5ed1f68b46)
