1 * Freescale i.MX/MXC GPIO controller
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
16 gpio0: gpio@73f84000 {
17 compatible = "fsl,imx51-gpio", "fsl,imx31-gpio";
18 reg = <0x73f84000 0x4000>;
