Texas Instruments Palmas family power button module

This module is part of the Palmas family of PMICs. For more details
about the whole chip see:
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.
  NOTE: This depends on OTP support and POWERHOLD signal configuration
  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
  a press for debouncing purposes. NOTE: This depends on specific
  Palmas variation capability. Valid values are 15, 100, 500 and 1000.

Example:

&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>;
	};
};
