usb-c-connector

Vendor: Generic or vendor-independent

Note

An implementation of a driver matching this compatible is available in subsys/usb/usb_c/usbc_stack.c.

Description

A USB Type-C connector node represents a physical USB Type-C connector.
It should be a child of a USB-C interface controller or a separate node
when it is attached to both MUX and USB-C interface controller.

This is based on Linux, documentation:
  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/connector/usb-connector.yaml?h=v5.19&id=3d7cb6b04c3f3115719235cc6866b10326de34cd

Example:

USB-C connector attached to a STM32 UCPD typec port controller, which has
power delivery support and enables SINK.

vbus1: vbus {
    compatible = "zephyr,usb-c-vbus-adc";
    io-channels = <&adc2 8>;
    output-ohms = <49900>;
    full-ohms = <(330000 + 49900)>;
};

ports {
    #address-cells = <1>;
    #size-cells = <0>;
    port1: usb-c-port@1 {
        compatible = "usb-c-connector";
        reg = <1>;
        tcpc = <&ucpd1>;
        vbus = <&vbus1>;
        power-role = "sink";
        sink-pdos = <PDO_FIXED(5000, 2000, PDO_FIXED_USB_COMM)
                     PDO_VAR(5000, 12000, 2000)>;
        op-sink-microwatt = <10000000>;
    };
};
