+National Instruments Ettus Research USRP E3x0 button driver
+
+This module is part of the NI Ettus Research USRP E3x0 SDR.
+
+This module provides a simple power button event via two interrupts.
+
+Required properties:
+- compatible: should be one of the following
+  - "ettus,e3x0-button": For devices such as the NI Ettus Research USRP E3x0
+- interrupts: should be one of the following
+  - <0 30 1>, <0 31 1>: For devices such as the NI Ettus Research USRP E3x0
+- interrupt-names: should be one of the following
+  - "press", "release": For devices such as the NI Ettus Research USRP E3x0
+
+Note: Interrupt numbers might vary depending on the FPGA configuration.
+
+Example:
+	button {
+		compatible = "ettus,e3x0-button";
+		interrupt-parent = <&intc>;
+		interrupts = <0 30 1>, <0 31 1>;
+		interrupt-names = "press", "release";
+	}
