Texas Instruments TWL family (twl4030) pwrbutton module
This module is part of the TWL4030. For more details about the whole
chip see Documentation/devicetree/bindings/mfd/twl-familly.txt.
This module provides a simple power button event via an Interrupt.
Required properties:
- compatible: should be one of the following
- "ti,twl4030-pwrbutton": For controllers compatible with twl4030
- interrupts: should be one of the following
- <8>: For controllers compatible with twl4030
Example:
&twl {
twl_pwrbutton: pwrbutton {
compatible = "ti,twl4030-pwrbutton";
interrupts = <8>;
};
};
