1* Freescale i.MX/MXC GPIO controller
2
3Required properties:
4- compatible : Should be "fsl,<soc>-gpio"
5- reg : Address and length of the register set for the device
6- interrupts : Should be the port interrupt shared by all 32 pins, if
7  one number.  If two numbers, the first one is the interrupt shared
8  by low 16 pins and the second one is for high 16 pins.
9- gpio-controller : Marks the device node as a gpio controller.
10- #gpio-cells : Should be two.  The first cell is the pin number and
11  the second cell is used to specify optional parameters (currently
12  unused).

16gpio0: gpio@73f84000 {
17	compatible = "fsl,imx51-gpio", "fsl,imx31-gpio";
18	reg = <0x73f84000 0x4000>;
19	interrupts = <50 51>;
20	gpio-controller;
21	#gpio-cells = <2>;
