- * 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>;
- };
- ...
- };
