1* Freescale VF610 PORT/GPIO module
2
3The Freescale PORT/GPIO modules are two adjacent modules providing GPIO
4functionality. Each pair serves 32 GPIOs. The VF610 has 5 instances of
5each, and each PORT module has its own interrupt.

7Required properties for GPIO node:
8- compatible : Should be "fsl,<soc>-gpio", below is supported list:
9	       "fsl,vf610-gpio"
10	       "fsl,imx7ulp-gpio"
11- reg : The first reg tuple represents the PORT module, the second tuple
12  the GPIO module.
13- interrupts : Should be the port interrupt shared by all 32 pins.
14- gpio-controller : Marks the device node as a gpio controller.
15- #gpio-cells : Should be two. The first cell is the pin number and
16  the second cell is used to specify the gpio polarity:
17      0 = active high
18      1 = active low
19- interrupt-controller: Marks the device node as an interrupt controller.
20- #interrupt-cells : Should be 2.  The first cell is the GPIO number.
21  The second cell bits[3:0] is used to specify trigger type and level flags:
22      1 = low-to-high edge triggered.
23      2 = high-to-low edge triggered.
24      4 = active high level-sensitive.
25      8 = active low level-sensitive.
26
27Optional properties:
28-clocks:	Must contain an entry for each entry in clock-names.
29		See common clock-bindings.txt for details.
30-clock-names:	A list of clock names. For imx7ulp, it must contain
31		"gpio", "port".
32
33Note: Each GPIO port should have an alias correctly numbered in "aliases"
34node.
