   4 Subject: [PATCH] overlays: dpi18 and dpi24 vc4 compatibility
   5
   6 The dpi overlays use the fb device tree node as a place to hang the
   7 necessary pinctrl changes. With one of the VC4 overlays loaded, the
   8 fb node is disabled so the changes have no effect.
   9
  10 Modify the overlays to also use the vc4 node, to cover both use
  11 cases.
