* 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>; |
|
}; |
|
... |
|
};
