Properties for the MDIO bus multiplexer/glue of Amlogic G12a SoC family. This is a special case of a MDIO bus multiplexer. It allows to choose between the internal mdio bus leading to the embedded 10/100 PHY or the external MDIO bus. Required properties in addition to the generic multiplexer properties: - compatible : amlogic,g12a-mdio-mux - reg: physical address and length of the multiplexer/glue registers - clocks: list of clock phandle, one for each entry clock-names. - clock-names: should contain the following: * "pclk" : peripheral clock. * "clkin0" : platform crytal * "clkin1" : SoC 50MHz MPLL Example : mdio_mux: mdio-multiplexer@4c000 { compatible = "amlogic,g12a-mdio-mux"; reg = <0x0 0x4c000 0x0 0xa4>; clocks = <&clkc CLKID_ETH_PHY>, <&xtal>, <&clkc CLKID_MPLL_5OM>; clock-names = "pclk", "clkin0", "clkin1"; mdio-parent-bus = <&mdio0>; #address-cells = <1>; #size-cells = <0>; ext_mdio: mdio@0 { reg = <0>; #address-cells = <1>; #size-cells = <0>; }; int_mdio: mdio@1 { reg = <1>; #address-cells = <1>; #size-cells = <0>; internal_ephy: ethernet-phy@8 { compatible = "ethernet-phy-id0180.3301", "ethernet-phy-ieee802.3-c22"; interrupts = ; reg = <8>; max-speed = <100>; }; }; };
