   1 * Synopsys ARC EMAC 10/100 Ethernet driver (EMAC)
   2
   3 Required properties:
   4 - compatible: Should be "snps,arc-emac"
   5 - reg: Address and length of the register set for the device
   6 - interrupts: Should contain the EMAC interrupts
   7 - clock-frequency: CPU frequency. It is needed to calculate and set polling
   8 period of EMAC.
   9 - max-speed: see ethernet.txt file in the same directory.
  10 - phy: see ethernet.txt file in the same directory.
  11
  12 Child nodes of the driver are the individual PHY devices connected to the
  13 MDIO bus. They must have a "reg" property given the PHY address on the MDIO bus.

  17         ethernet@c0fc2000 {
  18                 compatible = "snps,arc-emac";
  19                 reg = <0xc0fc2000 0x3c>;
  20                 interrupts = <6>;
  21                 mac-address = [ 00 11 22 33 44 55 ];
  22                 clock-frequency = <80000000>;
  23                 max-speed = <100>;
  24                 phy = <&phy0>;
  25
  26                 #address-cells = <1>;
  27                 #size-cells = <0>;
  28                 phy0: ethernet-phy@0 {
  29                         reg = <1>;
  30                 };
  31         };
