Single child nodes in OF graph don't need an address and now dtc will warn about this: Warning (graph_child_address): /soc/aips@50000000/ldb@53fa8008/lvds-channel@0: graph node has single child node 'port@0', #address-cells/#size-cells are not necessary Since the LDB should always have an output port, fix the warning by adding the output port, 2, to the DT.
