This module is part of the Palmas family of PMICs. For more details
about the whole chip see:

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
- 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.

  which the power button should be kept pressed for Palmas to register
  a press for debouncing purposes. NOTE: This depends on specific

&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>;
