-Subject: [PATCH] drm/vc4: plane: Create overlays for any CRTC
-
-Now that we have everything in place, we can now register all the overlay
-planes that can be assigned to all the CRTCs.
-
-This has two side effects:
-
-  - The number of overlay planes is reduced from 24 to 8. This is temporary
-    and will be increased again in the next patch.
-
-  - The ID of the various planes is changed again, and we will now have all
-    the primary planes, then all the overlay planes and finally the cursor
-    planes. This shouldn't cause any issue since the ordering between
-    primary, overlay and cursor planes is preserved.
