+Samsung micro-USB 11-pin connector
+==================================
+
+Samsung micro-USB 11-pin connector is an extension of micro-USB connector.
+It is present in multiple Samsung mobile devices.
+It has additional pins to route MHL traffic simultanously with USB.
+
+The bindings are superset of usb-connector bindings for micro-USB connector[1].
+
+Required properties:
+- compatible: must be: "samsung,usb-connector-11pin", "usb-b-connector",
+- type: must be "micro".
+
+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
+ has assigned OF graph port number as follows:
+ 0: High Speed (HS),
+ 3: Mobile High-Definition Link (MHL), specific to 11-pin Samsung micro-USB.
+
+[1]: bindings/connector/usb-connector.txt
+
+Example
+-------
+
+Micro-USB connector with HS lines routed via controller (MUIC) and MHL lines
+connected to HDMI-MHL bridge (sii8620):
+
+muic-max77843@66 {
+ ...
+ usb_con: connector {
+ compatible = "samsung,usb-connector-11pin", "usb-b-connector";
+ label = "micro-USB";
+ type = "micro";
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@3 {
+ reg = <3>;
+ usb_con_mhl: endpoint {
+ remote-endpoint = <&sii8620_mhl>;
+ };
+ };
+ };
+ };
+};
