+National Instruments Ettus Research USRP E3x0 poweroff driver
+
+This module is part of the NI Ettus Research USRP E3x0 SDR.
+
+Required properties:
+- compatible: should be one of the following
+  - "ettus,e3x0-poweroff": For devices such as the NI Ettus Research USRP E3x0
+- syscon: this is the phandle to the register map node
+
+Note: Addresses may vary depending on the FPGA configuration
+
+Example:
+	poweroff0: poweroff@40300000 {
+		compatible = "ettus,e3x0-poweroff";
+		syscon = <&regmapnode>;
+	};
