1 * Palmas 32KHz clocks *
2
3 Palmas device has two clock output pins for 32KHz, KG and KG_AUDIO.
4
5 This binding uses the common clock binding ./clock-bindings.txt.
6
7 Required properties:
8 - compatible : "ti,palmas-clk32kg" for clk32kg clock
9 "ti,palmas-clk32kgaudio" for clk32kgaudio clock
10 - #clock-cells : shall be set to 0.
11
12 Optional property:
13 - ti,external-sleep-control: The external enable input pins controlled the
14 enable/disable of clocks. The external enable input pins ENABLE1,
15 ENABLE2 and NSLEEP. The valid values for the external pins are:
16 PALMAS_EXT_CONTROL_PIN_ENABLE1 for ENABLE1 pin
17 PALMAS_EXT_CONTROL_PIN_ENABLE2 for ENABLE2 pin
18 PALMAS_EXT_CONTROL_PIN_NSLEEP for NSLEEP pin
19 Option 0 or missing this property means the clock is enabled/disabled
20 via register access and these pins do not have any control.
21 The macros of external control pins for DTS is defined at
22 dt-bindings/mfd/palmas.h
23
24 Example:
25 #include <dt-bindings/mfd/palmas.h>
26 ...
27 palmas: tps65913@58 {
28 ...
29 clk32kg: palmas_clk32k@0 {
30 compatible = "ti,palmas-clk32kg";
31 #clock-cells = <0>;
32 ti,external-sleep-control = <PALMAS_EXT_CONTROL_PIN_NSLEEP>;
33 };
34 ...
35 };
