Required properties:

- compatible: For external switch chips, compatible string must be exactly one
  of: "brcm,bcm5325"
      "brcm,bcm53115"
      "brcm,bcm53125"

      "brcm,bcm3384-switch"
      "brcm,bcm6328-switch"
      "brcm,bcm6368-switch" and the mandatory "brcm,bcm63xx-switch"

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>;
			duplex-full;
		};
	};

	mdio0: mdio@10000000 {
		compatible = "brcm,unimac-mdio";
		#address-cells = <1>;
		#size-cells = <0>;

		switch0: ethernet-switch@30 {
			compatible = "brcm,bcm53125";
			#address-cells = <1>;
			#size-cells = <0>;

			ports {
				port0@0 {
					reg = <0>;
					label = "lan1";
				};

				port1@1 {
					reg = <1>;
					label = "lan2";
				};

				port5@5 {
					reg = <5>;
					label = "cable-modem";
					fixed-link {
						speed = <1000>;
						duplex-full;
					};
					phy-mode = "rgmii-txid";
				};

				port8@8 {
					reg = <8>;
					label = "cpu";
					fixed-link {
						speed = <1000>;
						duplex-full;
					};
					phy-mode = "rgmii-txid";
					ethernet = <&eth0>;
				};
			};
		};
	};
