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.
