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