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>;
};
};
};
};
};
