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

   13 
   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.
   31  - silabs,skip-recall: Do not perform NVM->RAM recall operation. It will rely
   32                        on hardware loading of RAM from NVM at power on.
   33 
   34 Example:
   35         si570: clock-generator@5d {
   36                 #clock-cells = <0>;
   37                 compatible = "silabs,si570";
   38                 temperature-stability = <50>;
   39                 reg = <0x5d>;
   40                 factory-fout = <156250000>;
   41         };
