  1. TI SoC Davinci/Keystone2 MDIO Controller Device Tree Bindings
  2. ---------------------------------------------------
  3. Required properties:
  4. - compatible : Should be "ti,davinci_mdio" or "ti,keystone_mdio"
  5. - reg : physical base address and size of the davinci mdio
  6. registers map
  7. - bus_freq : Mdio Bus frequency
  8. Optional properties:
  9. - ti,hwmods : Must be "davinci_mdio"
  10. Note: "ti,hwmods" field is used to fetch the base address and irq
  11. resources from TI, omap hwmod data base during device registration.
  12. Future plan is to migrate hwmod data base contents into device tree
  13. blob so that, all the required data will be used from device tree dts
  14. file.
  15. Examples:
  16. mdio: davinci_mdio@4A101000 {
  17. compatible = "ti,davinci_mdio";
  18. reg = <0x4A101000 0x1000>;
  19. bus_freq = <1000000>;
  20. };
  21. (or)
  22. mdio: davinci_mdio@4A101000 {
  23. compatible = "ti,davinci_mdio";
  24. ti,hwmods = "davinci_mdio";
  25. bus_freq = <1000000>;
  26. };
