-USB Connector
-=============
-
-A USB connector node represents a physical USB connector. It should be
-a child of a USB interface controller.
-
-Required properties:
-- compatible: describes type of the connector, must be one of:
- "usb-a-connector",
- "usb-b-connector",
- "usb-c-connector".
-
-Optional properties:
-- label: symbolic name for the connector,
-- type: size of the connector, should be specified in case of USB-A, USB-B
- non-fullsize connectors: "mini", "micro".
-- self-powered: Set this property if the usb device that has its own power
- source.
-
-Optional properties for usb-b-connector:
-- id-gpios: an input gpio for USB ID pin.
-- vbus-gpios: an input gpio for USB VBUS pin, used to detect presence of
- VBUS 5V.
- see gpio/gpio.txt.
-- vbus-supply: a phandle to the regulator for USB VBUS if needed when host
- mode or dual role mode is supported.
- Particularly, if use an output GPIO to control a VBUS regulator, should
- model it as a regulator.
- see regulator/fixed-regulator.yaml
-- pinctrl-names : a pinctrl state named "default" is optional
-- pinctrl-0 : pin control group
- see pinctrl/pinctrl-bindings.txt
-
-Optional properties for usb-c-connector:
-- power-role: should be one of "source", "sink" or "dual"(DRP) if typec
- connector has power support.
-- try-power-role: preferred power role if "dual"(DRP) can support Try.SNK
- or Try.SRC, should be "sink" for Try.SNK or "source" for Try.SRC.
-- data-role: should be one of "host", "device", "dual"(DRD) if typec
- connector supports USB data.
-
-Required properties for usb-c-connector with power delivery support:
-- source-pdos: An array of u32 with each entry providing supported power
- source data object(PDO), the detailed bit definitions of PDO can be found
- in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.2
- Source_Capabilities Message, the order of each entry(PDO) should follow
- the PD spec chapter 6.4.1. Required for power source and power dual role.
- User can specify the source PDO array via PDO_FIXED/BATT/VAR/PPS_APDO()
- defined in dt-bindings/usb/pd.h.
-- sink-pdos: An array of u32 with each entry providing supported power
- sink data object(PDO), the detailed bit definitions of PDO can be found
- in "Universal Serial Bus Power Delivery Specification" chapter 6.4.1.3
- Sink Capabilities Message, the order of each entry(PDO) should follow
- the PD spec chapter 6.4.1. Required for power sink and power dual role.
- User can specify the sink PDO array via PDO_FIXED/BATT/VAR/PPS_APDO() defined
- in dt-bindings/usb/pd.h.
-- op-sink-microwatt: Sink required operating power in microwatt, if source
- can't offer the power, Capability Mismatch is set. Required for power
- sink and power dual role.
-
-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 multiple data buses every bus
- has assigned OF graph port number as follows:
- 0: High Speed (HS), present in all connectors,
- 1: Super Speed (SS), present in SS capable connectors,
- 2: Sideband use (SBU), present in USB-C.
-
-Examples
---------
-
-1. Micro-USB connector with HS lines routed via controller (MUIC):
-
-muic-max77843@66 {
- ...
- usb_con: connector {
- compatible = "usb-b-connector";
- label = "micro-USB";
- type = "micro";
- };
-};
-
-2. USB-C connector attached to CC controller (s2mm005), HS lines routed
-to companion PMIC (max77865), SS lines to USB3 PHY and SBU to DisplayPort.
-DisplayPort video lines are routed to the connector via SS mux in USB3 PHY.
-
-ccic: s2mm005@33 {
- ...
- usb_con: connector {
- compatible = "usb-c-connector";
- label = "USB-C";
-
- ports {
- #address-cells = <1>;
- #size-cells = <0>;
-
- port@0 {
- reg = <0>;
- usb_con_hs: endpoint {
- remote-endpoint = <&max77865_usbc_hs>;
- };
- };
- port@1 {
- reg = <1>;
- usb_con_ss: endpoint {
- remote-endpoint = <&usbdrd_phy_ss>;
- };
- };
- port@2 {
- reg = <2>;
- usb_con_sbu: endpoint {
- remote-endpoint = <&dp_aux>;
- };
- };
- };
- };
-};
-
-3. USB-C connector attached to a typec port controller(ptn5110), which has
-power delivery support and enables drp.
-
-typec: ptn5110@50 {
- ...
- usb_con: connector {
- compatible = "usb-c-connector";
- label = "USB-C";
- power-role = "dual";
- try-power-role = "sink";
- source-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)>;
- sink-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)
- PDO_VAR(5000, 12000, 2000)>;
- op-sink-microwatt = <10000000>;
- };
-};
