* Allwinner A10 MDIO Ethernet Controller interface
|
|
|
|
Required properties:
|
|
- compatible: should be "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@01c0b080 {
|
|
compatible = "allwinner,sun4i-mdio";
|
|
reg = <0x01c0b080 0x14>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
};
|
|
|
|
And at the board level:
|
|
|
|
mdio@01c0b080 {
|
|
phy-supply = <®_emac_3v3>;
|
|
|
|
phy0: ethernet-phy@0 {
|
|
reg = <0>;
|
|
};
|
|
};
