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.
