- 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>;
- };
