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>; }; };
