Hisilicon Fast Ethernet MDIO Controller interface Required properties: - compatible: should be "hisilicon,hisi-femac-mdio". - reg: address and length of the register set for the device. - clocks: A phandle to the reference clock for this device. - PHY subnode: inherits from phy binding [1] [1] Documentation/devicetree/bindings/net/phy.txt Example: mdio: mdio@10091100 { compatible = "hisilicon,hisi-femac-mdio"; reg = <0x10091100 0x10>; clocks = <&crg HI3516CV300_MDIO_CLK>; #address-cells = <1>; #size-cells = <0>; phy0: phy@1 { reg = <1>; }; };
