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. - -Signed-off-by: Maxime Ripard <maxime@cerno.tech> ---- - drivers/gpu/drm/vc4/vc4_plane.c | 35 +++++++++++++++++---------------- - 1 file changed, 18 insertions(+), 17 deletions(-) - ---- a/drivers/gpu/drm/vc4/vc4_plane.c -+++ b/drivers/gpu/drm/vc4/vc4_plane.c -@@ -1454,26 +1454,27 @@ int vc4_plane_create_additional_planes(s - struct drm_crtc *crtc; - unsigned int i; - -- drm_for_each_crtc(crtc, drm) { -- /* Set up some arbitrary number of planes.
