FWIW this is opposite vs what the (most common) DWC3 schema defines: (also true for mediatek,mtu3 and renesas,usb3-peri) -- Documentation/devicetree/bindings/usb/snps,dwc3-common.yaml ports: $ref: /schemas/graph.yaml#/properties/ports description: Those ports should be used with any connector to the data bus of this controller using the OF graph bindings specified if the "usb-role-switch" property is used. properties: port@0: $ref: /schemas/graph.yaml#/properties/port description: High Speed (HS) data bus. port@1: $ref: /schemas/graph.yaml#/properties/port description: Super Speed (SS) data bus.
