Binding for Maxim MAX77802 32k clock generator block
|
||||
|
||||
This is a part of device tree bindings of MAX77802 multi-function device.
|
||||
More information can be found in bindings/mfd/max77802.txt file.
|
||||
|
||||
The MAX77802 contains two 32.768khz clock outputs that can be controlled
|
||||
(gated/ungated) over I2C.
|
||||
|
||||
Following properties should be present in main device node of the MFD chip.
|
||||
|
||||
Required properties:
|
||||
- #clock-cells: From common clock binding; shall be set to 1.
|
||||
|
||||
Optional properties:
|
||||
- clock-output-names: From common clock binding.
|
||||
|
||||
Each clock is assigned an identifier and client nodes can use this identifier
|
||||
to specify the clock which they consume. Following indices are allowed:
|
||||
- 0: 32khz_ap clock,
|
||||
- 1: 32khz_cp clock.
|
||||
|
||||
Clocks are defined as preprocessor macros in dt-bindings/clock/maxim,max77802.h
|
||||
header and can be used in device tree sources.
|
||||
|
||||
Example: Node of the MFD chip
|
||||
|
||||
max77802: max77802@09 {
|
||||
compatible = "maxim,max77802";
|
||||
interrupt-parent = <&wakeup_eint>;
|
||||
interrupts = <26 0>;
|
||||
reg = <0x09>;
|
||||
#clock-cells = <1>;
|
||||
|
||||
/* ... */
|
||||
};
|
||||
|
||||
Example: Clock consumer node
|
||||
|
||||
foo@0 {
|
||||
compatible = "bar,foo";
|
||||
/* ... */
|
||||
clock-names = "my-clock";
|
||||
clocks = <&max77802 MAX77802_CLK_32K_AP>;
|
||||
};
