See Documentation/devicetree/bindings/net/dsa/dsa.txt for a list of additional

required and optional properties.



Examples:



Ethernet switch connected via MDIO to the host, CPU port wired to eth0:



	eth0: ethernet@10001000 {

		compatible = "brcm,unimac";

		reg = <0x10001000 0x1000>;



		fixed-link {

			speed = <1000>;

			full-duplex;

		};

	};



	mdio0: mdio@10000000 {

		compatible = "brcm,unimac-mdio";

		#address-cells = <1>;

		#size-cells = <0>;



		switch0: ethernet-switch@1e {

			compatible = "brcm,bcm53125";

			reg = <30>;

			#address-cells = <1>;

			#size-cells = <0>;



			ports {

				#address-cells = <1>;

				#size-cells = <0>;



				port0@0 {

					reg = <0>;

					label = "lan1";

				};



				port1@1 {

					reg = <1>;

					label = "lan2";

				};



				port5@5 {

					reg = <5>;

					label = "cable-modem";

					fixed-link {

						speed = <1000>;

						full-duplex;

					};

					phy-mode = "rgmii-txid";
