+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".
+
+Optional properties:
+- label: symbolic name for the connector.
+
+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 :
+
+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>;
+                               };
+                       };
+               };
+       };
+};
