40Examples:
41
42Ethernet switch connected via MDIO to the host, CPU port wired to eth0:
43
44 eth0: ethernet@10001000 {
45 compatible = "brcm,unimac";
46 reg = <0x10001000 0x1000>;
47
48 fixed-link {
49 speed = <1000>;
50 duplex-full;
51 };
52 };
53
54 mdio0: mdio@10000000 {
55 compatible = "brcm,unimac-mdio";
56 #address-cells = <1>;
57 #size-cells = <0>;
58
59 switch0: ethernet-switch@30 {
