Definition is inspired from mediatek,mtu3.yaml. This fixes some errors seen when running "make dtbs_check": ... 'port' does not match any of the regexes: 'pinctrl-[0-9]+' From schema: ... Documentation/devicetree/bindings/usb/dwc2.yaml Note: add dependencies so that 'usb-role-switch' without port is valid or both must be present.
