  1. Binding for Silicon Labs 570, 571, 598 and 599 programmable
  2. I2C clock generators.
  3. Reference
  4. This binding uses the common clock binding[1]. Details about the devices can be
  5. found in the data sheets[2][3].

  11. Required properties:
  12. - compatible: Shall be one of "silabs,si570", "silabs,si571",
  13. "silabs,si598", "silabs,si599"
  14. - reg: I2C device address.
  15. - #clock-cells: From common clock bindings: Shall be 0.
  16. - factory-fout: Factory set default frequency. This frequency is part specific.
  17. The correct frequency for the part used has to be provided in
  18. order to generate the correct output frequencies. For more
  19. details, please refer to the data sheet.
  20. - temperature-stability: Temperature stability of the device in PPM. Should be
  21. one of: 7, 20, 50 or 100.
  22. Optional properties:
  23. - clock-output-names: From common clock bindings. Recommended to be "si570".
  24. - clock-frequency: Output frequency to generate. This defines the output
  25. frequency set during boot. It can be reprogrammed during
  26. runtime through the common clock framework.
  27. Example:
  28. si570: clock-generator@5d {
  29. #clock-cells = <0>;
  30. compatible = "silabs,si570";
  31. temperature-stability = <50>;
  32. reg = <0x5d>;
  33. factory-fout = <156250000>;
  34. };
