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>;
