* 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>;
};
...
};
