+RFKILL switches connected to GPIO lines
+
+Required properties:
+- compatible : should be "rfkill-gpio".
+
+Each rfkill switch is represented as a sub-node of the rfkill-gpio device.
+Each node has a label property which represents the name of the corresponding
+rfkill device.
+
+RFKILL sub-node properties:
+- label :  (optional) The label for this rfkill switch.  If omitted, the label is
+  taken from the node name (excluding the unit address).
+- reset-gpio, shutdown-gpio :  Should specify the rfkill gpios for reset and
+  shutdown (see "Specifying GPIO information for devices" in
+  Documentation/devicetree/booting-without-of.txt).
+- type : enumerated type of the gpio (see include/linux/rfkill.h).
+- clock : (optional) name of the clock name associated with the rfkill switch
+  (see include/linux/rfkill-gpio.h)
+
+Examples:
+
+rfkill-switches {
+	compatible = "rfkill-gpio";
+
+	wifi {
+		label = "wifi";
+		reset-gpio = <&gpio 25 0>; /* Active high */
+		shutdown-gpio = <&gpio 85 0>; /* Active high */
+		type = <1>;
+	};
+
+	bt {
+		label = "bluetooth";
+		reset-gpio = <&gpio 17 0>; /* Active high */
+		shutdown-gpio = <&gpio 35 0>; /* Active high */
+		type = <1>;
+	};
+};
