But unfortunately it also added a regression on the Peach Pit when changing the port node names since the OF graph logic expects the port nodes to be always named 'port'. The Documentation/devicetree/bindings/graph.txt binding document says that when there is more than one port, '#address-cells', '#size-cells' and 'reg' properties should be used to number the port nodes.
