+Subject: [PATCH] overlays: dpi18 and dpi24 vc4 compatibility
+
+The dpi overlays use the fb device tree node as a place to hang the
+necessary pinctrl changes. With one of the VC4 overlays loaded, the
+fb node is disabled so the changes have no effect.
+
+Modify the overlays to also use the vc4 node, to cover both use
+cases.
