Subject: [PATCH] drm/vc4: Add support for DRM_FORMAT_P030 to vc4
|
|
planes
|
|
|
|
This currently doesn't handle non-zero source rectangles correctly,
|
|
but add support for DRM_FORMAT_P030 with DRM_FORMAT_MOD_BROADCOM_SAND128
|
|
modifier to planes when running on HVS5.
|
|
|
|
WIP still for source cropping SAND/P030 formats
