   1 * Allwinner A10 MDIO Ethernet Controller interface
   2
   3 Required properties:
   4 - compatible: should be "allwinner,sun4i-a10-mdio"
   5               (Deprecated: "allwinner,sun4i-mdio").
   6 - reg: address and length of the register set for the device.
   7
   8 Optional properties:
   9 - phy-supply: phandle to a regulator if the PHY needs one
  10
  11 Example at the SoC level:
  12 mdio@01c0b080 {
  13         compatible = "allwinner,sun4i-a10-mdio";
  14         reg = <0x01c0b080 0x14>;
  15         #address-cells = <1>;
  16         #size-cells = <0>;
  17 };
  18
  19 And at the board level:
  20
  21 mdio@01c0b080 {
  22         phy-supply = <&reg_emac_3v3>;
  23
  24         phy0: ethernet-phy@0 {
  25                 reg = <0>;
  26         };
  27 };
