Required nodes:
- any data bus to the connector should be modeled using the OF graph bindings
specified in bindings/graph.txt, unless the bus is between parent node and
- the connector. Since single connector can have multpile data buses every bus
+ the connector. Since single connector can have multiple data buses every bus
has assigned OF graph port number as follows:
0: High Speed (HS), present in all connectors,
1: Super Speed (SS), present in SS capable connectors,
