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].

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.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
si570: clock-generator@5d {
|
||
|
|
#clock-cells = <0>;
|
||
|
|
compatible = "silabs,si570";
|
||
|
|
temperature-stability = <50>;
|
||
|
|
reg = <0x5d>;
|
||
|
|
factory-fout = <156250000>;
|
||
|
|
};
