+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
+- interrupt-parent:
+ - a phandle to the interrupt controller that it is attached to.
+- 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";
+ }

+* Regulator Haptic Device Tree Bindings
+
+Required Properties:
+ - compatible : Should be "regulator-haptic"
+ - haptic-supply : Power supply to the haptic motor.
+ [*] refer Documentation/devicetree/bindings/regulator/regulator.txt
+
+ - max-microvolt : The maximum voltage value supplied to the haptic motor.
+ [The unit of the voltage is a micro]
+
+ - min-microvolt : The minimum voltage value supplied to the haptic motor.
+ [The unit of the voltage is a micro]
+
+Example:
+
+ haptics {
+ compatible = "regulator-haptic";
+ haptic-supply = <&motor_regulator>;
+ max-microvolt = <2700000>;
+ min-microvolt = <1100000>;
