This patch adds the driver and devicetree documentation for the Silicon Labs SI544 clock generator chip. This is an I2C controlled oscillator capable of generating clock signals ranging from 200kHz to 1500MHz.

|
Reference
|
|
This binding uses the common clock binding[1]. Details about the device can be
|
|
found in the datasheet[2].

|
Required properties:
|
|
- compatible: One of "silabs,si514a", "silabs,si514b" "silabs,si514c" according
|
|
to the speed grade of the chip.
|
|
- reg: I2C device address.
|
|
- #clock-cells: From common clock bindings: Shall be 0.
|
|
|
|
Optional properties:
|
|
- clock-output-names: From common clock bindings. Recommended to be "si544".
|
|
|
|
Example:
|
|
si544: clock-controller@55 {
|
|
reg = <0x55>;
|
|
#clock-cells = <0>;
|
|
compatible = "silabs,si544b";
|
|
};
