Hi,
this series was initially triggered by dtbs_check warnings. Despite [1]
rendering them invalid, this series still simplifies the DSI OF graphs on all
i.MX8M variants by adding an empty output endpoint.
Each board enabling DSI connection can simply reference the label.
Patch 5 uses applies this to MBa8Mx board.
Best regards,
Alexander

Also add a corresponding label so overlays can reference that node.

With the DSI output label in place, use the phandle directly.
