This leaves an incomplete graph as the TFP410 output has only half a connection. The result is the following warning: arch/arm/boot/dts/omap3-devkit8000-lcd70.dtb: Warning (graph_endpoint): /encoder0/ports/port@0/endpoint: graph connection to node '/ocp@68000000/dss@48050000/port/endpoint' is not bidirectional Fix this by defining multiple endpoints which is the correct way to show a 1 to many connection.
