+TI SoC Davinci MDIO Controller Device Tree Bindings
+---------------------------------------------------
+
+Required properties:
+- compatible : Should be "ti,davinci_mdio"
+- 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,cpsw";
+ reg = <0x4A101000 0x1000>;
+ bus_freq = <1000000>;
+ };
+
+(or)
+
+ mdio: davinci_mdio@4A101000 {
+ compatible = "ti,cpsw";
+ ti,hwmods = "davinci_mdio";
+ bus_freq = <1000000>;
+ };
