This is implied (and may be in a parent node), so remove it.
+- interrupt-controller: Marks the device node as an interrupt controller. +- #interrupt-cells: Must be <2>. + +- gpio-controller : Marks the device node as a gpio controller. +- #gpio-cells : Must be <2>. The first cell is the pin number and
Some space before tabs here.
+ the second cell is used to specify the gpio active
+ state.
+
+Optional properties:
+--------------------
+gpio-line-names: Single string containing the name of the GPIO line.
+
+The GPIO-controller module is represented as part of the top-level PMIC
+node. The device exposes a single GPIO line.
+
+For device-tree bindings of other sub-modules (regulator, power supply,
+LEDs and onkey) refer to the binding documents under the respective
+sub-system directories.
+
+For more details on GPIO bindings, please refer to the generic GPIO DT
+binding document <devicetree/bindings/gpio/gpio.txt>.
