1 Samsung micro-USB 11-pin connector
2 ==================================
3
4 Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
5 It is present in multiple Samsung mobile devices.
6 It has additional pins to route MHL traffic simultanously with USB.
7
8 The bindings are superset of usb-connector bindings for micro-USB connector[1].
9
10 Required properties:
11 - compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
12 - type: must be "micro".
13
14 Required 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.
