TI SoC Davinci/Keystone2 MDIO Controller Device Tree Bindings --------------------------------------------------- Required properties: - compatible : Should be "ti,davinci_mdio" and "ti,keystone_mdio" for Keystone 2 SoCs and "ti,cpsw-mdio" for am335x, am472x, am57xx/dra7, dm814x SoCs and "ti,am4372-mdio" for am472x SoC - reg : physical base address and size of the davinci mdio registers map - bus_freq : Mdio Bus frequency Optional properties: - ti,hwmods : Must be "davinci_mdio" Note: "ti,hwmods" field is used to fetch the base address and irq resources from TI, omap hwmod data base during device registration. Future plan is to migrate hwmod data base contents into device tree blob so that, all the required data will be used from device tree dts file. Examples: mdio: davinci_mdio@4a101000 { compatible = "ti,davinci_mdio"; reg = <0x4A101000 0x1000>; bus_freq = <1000000>; }; (or) mdio: davinci_mdio@4a101000 { compatible = "ti,davinci_mdio"; ti,hwmods = "davinci_mdio"; bus_freq = <1000000>; };
