* Broadcom Starfighter 2 integrated switch

See dsa/brcm,bcm7445-switch-v4.0.yaml for the documentation.

*Deprecated* binding required properties:

- dsa,mii-bus: phandle to the MDIO bus controller, see dsa/dsa.txt
- dsa,ethernet: phandle to the CPU network interface controller, see dsa/dsa.txt
- #address-cells: must be 2, see dsa/dsa.txt

Example using the old DSA DeviceTree binding:

switch_top@f0b00000 {
	compatible = "simple-bus";
	#size-cells = <1>;
	#address-cells = <1>;
	ranges = <0 0xf0b00000 0x40804>;

	ethernet_switch@0 {
		compatible = "brcm,bcm7445-switch-v4.0";
		#size-cells = <0>;
		#address-cells = <2>;
		reg = <0x0 0x40000
			0x40000 0x110
			0x40340 0x30
			0x40380 0x30
			0x40400 0x34
			0x40600 0x208>;
		interrupts = <0 0x18 0
				0 0x19 0>;
		brcm,num-gphy = <1>;
		brcm,num-rgmii-ports = <2>;
		brcm,fcb-pause-override;
		brcm,acb-packets-inflight;

		...
		switch@0 {
			reg = <0 0>;
			#size-cells = <0>;
			#address-cells = <1>;

			port@0 {
				label = "gphy";
				reg = <0>;
				brcm,use-bcm-hdr;
			};
			...
		};
	};
};
