- Switch Register Access block base, the second is the port 5/4 mux
- configuration register and the third one is the SGMII configuration
- and status register base address.
-
- - interrupts: a total of 13 interrupts must be specified, in the following
- order: port 0-5, 7-8 link status change, then the integrated PHY interrupt,
- then the timestamping interrupt and the sleep timer interrupts for ports
- 5,7,8.

-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";
