1APM X-Gene SoC MDIO node2 3MDIO node is defined to describe on-chip MDIO controller.4 5Required properties:6 - compatible: Must be "apm,xgene-mdio-rgmii" or "apm,xgene-mdio-xfi"7 - #address-cells: Must be <1>.8 - #size-cells: Must be <0>.9 - reg: Address and length of the register set10 - clocks: Reference to the clock entry11 12For the phys on the mdio bus, there must be a node with the following fields:13 - compatible: PHY identifier. Please refer ./phy.txt for the format.14 - reg: The ID number for the phy.15 16Example:17 18 mdio: mdio@17020000 {19 compatible = "apm,xgene-mdio-rgmii";20 #address-cells = <1>;21 #size-cells = <0>;22 reg = <0x0 0x17020000 0x0 0xd100>;23 clocks = <&menetclk 0>;24 };25 26 /* Board-specific peripheral configurations */27 &mdio {28 menetphy: phy@3 {29 reg = <0x3>;30 };31 sgenet0phy: phy@4 {32 reg = <0x4>;33 };34 sgenet1phy: phy@5 {35 reg = <0x5>;36 };37 };38
