   1TI SoC Davinci MDIO Controller Device Tree Bindings
   2---------------------------------------------------
   3
   4Required properties:
   5- compatible            : Should be "ti,davinci_mdio"
   6- reg                   : physical base address and size of the davinci mdio
   7                          registers map
   8- bus_freq              : Mdio Bus frequency
   9
  10Optional properties:
  11- ti,hwmods             : Must be "davinci_mdio"
  12
  13Note: "ti,hwmods" field is used to fetch the base address and irq
  14resources from TI, omap hwmod data base during device registration.
  15Future plan is to migrate hwmod data base contents into device tree
  16blob so that, all the required data will be used from device tree dts
  17file.

  19Examples:
  20
  21        mdio: davinci_mdio@4A101000 {
  22                compatible = "ti,cpsw";
  23                reg = <0x4A101000 0x1000>;
  24                bus_freq = <1000000>;
  25        };
  26
  27(or)
  28
  29        mdio: davinci_mdio@4A101000 {
  30                compatible = "ti,cpsw";
  31                ti,hwmods = "davinci_mdio";
  32                bus_freq = <1000000>;
  33        };
