+Bindings for the National Instruments 169445 GPIO NAND controller
+
+The 169445 GPIO NAND controller has two memory mapped GPIO registers, one
+for input (the ready signal) and one for output (control signals).  It is
+intended to be used with the GPIO NAND driver.
+
+Required properties:
+	- compatible: should be "ni,169445-nand-gpio"
+	- reg-names: must contain
+		"dat" - data register
+	- reg: address + size pairs describing the GPIO register sets;
+		order must correspond with the order of entries in reg-names
+	- #gpio-cells: must be set to 2. The first cell is the pin number and
+			the second cell is used to specify the gpio polarity:
+			0 = active high
+			1 = active low
+	- gpio-controller: Marks the device node as a gpio controller.
+
+Optional properties:
+	- no-output: disables driving output on the pins
+
+Examples:
+	gpio1: nand-gpio-out@1f300010 {
+		compatible = "ni,169445-nand-gpio";
+		reg = <0x1f300010 0x4>;
+		reg-names = "dat";
+		gpio-controller;
+		#gpio-cells = <2>;
+	};
+
+	gpio2: nand-gpio-in@1f300014 {
+		compatible = "ni,169445-nand-gpio";
+		reg = <0x1f300014 0x4>;
+		reg-names = "dat";
+		gpio-controller;
+		#gpio-cells = <2>;
+		no-output;
+	};
