-Subject: [PATCH 716/806] drm/vc4: Take margin setup into account when updating
- planes
-
-Commit 666e73587f90f42d90385c1bea1009a650bf73f4 upstream.
-
-Applyin margins is just a matter of scaling all planes appropriately
-and adjusting the CRTC X/Y offset to account for the
-left/right/top/bottom borders.
-
-Create a vc4_plane_margins_adj() function doing that and call it from
-vc4_plane_setup_clipping_and_scaling() so that we are ready to attach
-margins properties to the HDMI connector.
