-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>;
- };
