- fdt_get_phy_addr - Return the Ethernet PHY address
- Convenience function to return the PHY address of an

- @path full path to the network device node
- @return PHY address, or -1 if it does not exist
- Usage examples:
- Get PHY address of eth0 for a Kirkwood board as defined in kirkwood.dtsi
int phyaddr;
char *eth0_path = "/ocp@f1000000/ethernet-controller@72000";
phyaddr = fdt_get_phy_addr(eth0_path);
- Get PHY address of eth1 for a Armada 38x board as defined
- in armada-38x.dtsi
int phyaddr;
char *eth1_path = "/soc/ethernet@30000";
phyaddr = fdt_get_phy_addr(eth1_path);- */
