It allows you to configure the switch's registers using the standard MDIO interface. Since the device is connected over USB, there is no strict requirement of having a device tree representation of the device. But in order to use it with the mv88e6xxx driver, you need a device tree node in which to place the switch definition. allOf: - $ref: "mdio.yaml#" properties: compatible: const: usb1286,1fa4 reg: maxItems: 1 description: The USB port number on the host controller required: - compatible - reg - "#address-cells" - "#size-cells" unevaluatedProperties: false examples: - | /* USB host controller */ usb { #address-cells = <1>; #size-cells = <0>; mdio@1 { compatible = "usb1286,1fa4"; reg = <1>; #address-cells = <1>; #size-cells = <0>; switch@0 { compatible = "marvell,mv88e6190"; reg = <0x0>; ports { /* Port definitions */ }; mdio { /* PHY definitions */ }; }; }; };
