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.

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>;
