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.yaml



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>;

				};

			};

		};

	};

};
