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>;
};
};

|
Property to identify that a device can be used as wake up source.
When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.
Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.
|
|
|
Automatically configure the device for runtime power management after the
init function runs.
|
|
