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 the gpio polarity:
14 - interrupt-controller: Marks the device node as an interrupt controller.
15 - #interrupt-cells : Should be 2. The first cell is the GPIO number.
16 The second cell bits[3:0] is used to specify trigger type and level flags:
17 1 = low-to-high edge triggered.
18 2 = high-to-low edge triggered.
19 4 = active high level-sensitive.
20 8 = active low level-sensitive.
23 - clocks: the clock for clocking the GPIO silicon
