* Palmas 32KHz clocks *
|
||
|
|
|
||
|
|
Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO.
|
||
|
|
|
||
|
|
This binding uses the common clock binding ./clock-bindings.txt.
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible : "ti,palmas-clk32kg" for clk32kg clock
|
||
|
|
"ti,palmas-clk32kgaudio" for clk32kgaudio clock
|
||
|
|
- #clock-cells : shall be set to 0.
|
||
|
|
|
||
|
|
Optional property:
|
||
|
|
- ti,external-sleep-control: The external enable input pins controlled the
|
||
|
|
enable/disable of clocks. The external enable input pins ENABLE1,
|
||
|
|
ENABLE2 and NSLEEP. The valid values for the external pins are:
|
||
|
|
PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin
|
||
|
|
PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin
|
||
|
|
PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin
|
||
|
|
Option 0 or missing this property means the clock is enabled/disabled
|
||
|
|
via register access and these pins do not have any control.
|
||
|
|
The macros of external control pins for DTS is defined at
|
||
|
|
dt-bindings/mfd/palmas.h
|
||
|
|
|

|
|
Example:
|
||
|
|
#include <dt-bindings/mfd/palmas.h>

|
||
|
|
palmas: tps65913@58 {
|

|
|
...

|
|
clk32kg: palmas_clk32k@0 {
|
||
|
|
compatible = "ti,palmas-clk32kg";
|
||
|
|
#clock-cells = <0>;
|
||
|
|
ti,external-sleep-control = <PALMAS_EXT_CONTROL_PIN_NSLEEP>;
