Subject: [PATCH] dt-bindings: clock: Convert silabs,si570 to DT schema
Convert the Silicon Labs SI570 binding to DT schema format. It's a
straight-forward conversion.

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

-[3] Si598/599 Data Sheet
- https://www.silabs.com/Support%20Documents/TechnicalDocs/si598-99.pdf
-
-Required properties:
- - compatible: Shall be one of "silabs,si570", "silabs,si571",
- "silabs,si598", "silabs,si599"
- - reg: I2C device address.
- - #clock-cells: From common clock bindings: Shall be 0.
- - factory-fout: Factory set default frequency. This frequency is part specific.
- The correct frequency for the part used has to be provided in
- order to generate the correct output frequencies. For more
- details, please refer to the data sheet.
- - temperature-stability: Temperature stability of the device in PPM. Should be
- one of: 7, 20, 50 or 100.
-
-Optional properties:
- - clock-output-names: From common clock bindings. Recommended to be "si570".
- - clock-frequency: Output frequency to generate. This defines the output
- frequency set during boot. It can be reprogrammed during
- runtime through the common clock framework.
- - silabs,skip-recall: Do not perform NVM->RAM recall operation. It will rely
- on hardware loading of RAM from NVM at power on.
-
-Example:
- si570: clock-generator@5d {
- #clock-cells = <0>;
- compatible = "silabs,si570";
- temperature-stability = <50>;
- reg = <0x5d>;
- factory-fout = <156250000>;
- };
