1 * Allwinner A10 MDIO Ethernet Controller interface
4 - compatible: should be "allwinner,sun4i-mdio".
5 - reg: address and length of the register set for the device.
8 - phy-supply: phandle to a regulator if the PHY needs one
10 Example at the SoC level:
12 compatible = "allwinner,sun4i-mdio";
13 reg = <0x01c0b080 0x14>;
18 And at the board level:
21 phy-supply = <®_emac_3v3>;
23 phy0: ethernet-phy@0 {
