1Samsung micro-USB 11-pin connector
2==================================
3
4Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
5It is present in multiple Samsung mobile devices.
6It has additional pins to route MHL traffic simultanously with USB.
7
8The bindings are superset of usb-connector bindings for micro-USB connector[1].
9
10Required properties:
11- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
12- type: must be "micro".
13
14Required nodes:
15- any data bus to the connector should be modeled using the OF graph bindings
16  specified in bindings/graph.txt, unless the bus is between parent node and
17  the connector. Since single connector can have multpile data buses every bus
18  has assigned OF graph port number as follows:
19    0: High Speed (HS),
20    3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.
