Documentation/devicetree/bindings/mfd/palmas.txt.
|
|
|
|
This module provides a simple power button event via an Interrupt.
|
|
|
|
Required properties:
|
|
- compatible: should be one of the following
|
|
- "ti,palmas-pwrbutton": For Palmas compatible power on button
|
|
- interrupt-parent: Parent interrupt device, must be handle of palmas node.
|
|
- interrupts: Interrupt number of power button submodule on device.
|
|
|
|
Optional Properties:
|
|
|
|
- ti,palmas-long-press-seconds: Duration in seconds which the power
|
|
button should be kept pressed for Palmas to power off automatically.

|
|
on platform. Valid values are 6, 8, 10 and 12.
|
|
- ti,palmas-pwron-debounce-milli-seconds: Duration in milliseconds
|
|
which the power button should be kept pressed for Palmas to register

|
|
|
|
&palmas {
|
|
palmas_pwr_button: pwrbutton {
|
|
compatible = "ti,palmas-pwrbutton";
|
|
interrupt-parent = <&tps659038>;
|
|
interrupts = <1 IRQ_TYPE_EDGE_FALLING>;
|
|
ti,palmas-long-press-seconds = <12>;
|
|
ti,palmas-pwron-debounce-milli-seconds = <15>;
