* Allwinner A10 MDIO Ethernet Controller interface
Required properties:
- compatible: should be "allwinner,sun4i-a10-mdio"
(Deprecated: "allwinner,sun4i-mdio").
- reg: address and length of the register set for the device.
Optional properties:
- phy-supply: phandle to a regulator if the PHY needs one
Example at the SoC level:
mdio@1c0b080 {
compatible = "allwinner,sun4i-a10-mdio";
reg = <0x01c0b080 0x14>;
#address-cells = <1>;
#size-cells = <0>;
};
And at the board level:
mdio@1c0b080 {
phy-supply = <&reg_emac_3v3>;
phy0: ethernet-phy@0 {
reg = <0>;
};
};
