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";
|
|
};
