+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>;
+ };
+};
