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. |
|
- 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>; |
|
};
