APM X-Gene SoC MDIO node
MDIO node is defined to describe on-chip MDIO controller.
Required properties:
- compatible: Must be "apm,xgene-mdio-rgmii" or "apm,xgene-mdio-xfi"
- #address-cells: Must be <1>.
- #size-cells: Must be <0>.
- reg: Address and length of the register set
- clocks: Reference to the clock entry
For the phys on the mdio bus, there must be a node with the following fields:
- compatible: PHY identifier. Please refer ./phy.txt for the format.
- reg: The ID number for the phy.
Example:
mdio: mdio@17020000 {
compatible = "apm,xgene-mdio-rgmii";
#address-cells = <1>;
#size-cells = <0>;
reg = <0x0 0x17020000 0x0 0xd100>;
clocks = <&menetclk 0>;
};
/* Board-specific peripheral configurations */
&mdio {
menetphy: phy@3 {
reg = <0x3>;
};
sgenet0phy: phy@4 {
reg = <0x4>;
};
sgenet1phy: phy@5 {
reg = <0x5>;
};
};
