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	};
