+GPIO driver for DA9062 Power management IC (PMIC)
+
+Device has 5 GPIO pins which can be configured as GPIO as well as the
+special IO functions.
+
+Required properties:
+-------------------
+- compatible      : Should be "dlg,da9062-gpio".
+- gpio-controller : Marks the device node as a gpio controller.
+- #gpio-cells     : Should be two. The first cell is the pin number and the
+                    second cell is used to specify the gpio polarity.
+
+See Documentation/devicetree/bindings/gpio/gpio.txt for further information on
+GPIO bindings.
+
+Example:
+--------
+	pmic@58 {
+		...
+		pmic_gpio: gpio {
+			compatible = "dlg,da9062-gpio";
+			gpio-controller;
+			#gpio-cells = <2>;
+		};
+		...
+	};
