Kernel-4.18.0-80.el8_allwinner,sun4i-mdio

• 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>;
};

};
