 Required properties:
 - compatible		: Should be "nxp,lpc1850-gpio"
-- reg			: Address and length of the register set for the device
-- clocks		: Clock specifier (see clock bindings for details)
-- gpio-controller	: Marks the device node as a GPIO controller.
-- #gpio-cells 		: Should be two
-			  - First cell is the GPIO line number
-			  - Second cell is used to specify polarity
+- reg			: List of addresses and lengths of the GPIO controller
+			  register sets
+- reg-names		: Should be "gpio", "gpio-pin-ic", "gpio-group0-ic" and
+			  "gpio-gpoup1-ic"
+- clocks		: Phandle and clock specifier pair for GPIO controller
+- resets		: Phandle and reset specifier pair for GPIO controller
+- gpio-controller	: Marks the device node as a GPIO controller
+- #gpio-cells 		: Should be two:
+			  - The first cell is the GPIO line number
+			  - The second cell is used to specify polarity
+- interrupt-controller	: Marks the device node as an interrupt controller
+- #interrupt-cells	: Should be two:
+			  - The first cell is an interrupt number within
+			    0..9 range, for GPIO pin interrupts it is equal
+			    to 'nxp,gpio-pin-interrupt' property value of
+			    GPIO pin configuration, 8 is for GPIO GROUP0
+			    interrupt, 9 is for GPIO GROUP1 interrupt
