Every GPIO controller node must have #gpio-cells property defined,
this information will be used to translate gpio-specifiers.
See bindings/gpio/gpio.txt for details of how to specify GPIO
information for devices.

The GPIO module usually is connected to the SoC's internal interrupt
controller, see bindings/interrupt-controller/interrupts.txt (the
interrupt client nodes section) for details how to specify this GPIO
module's interrupt.

The GPIO module may serve as another interrupt controller (cascaded to
the SoC's internal interrupt controller). See the interrupt controller
nodes section in bindings/interrupt-controller/interrupts.txt for
details.

Required properties:
- compatible : "fsl,<CHIP>-gpio" followed by "fsl,mpc8349-gpio" for
83xx, "fsl,mpc8572-gpio" for 85xx and "fsl,mpc8610-gpio" for 86xx.
- #gpio-cells : Should be two. The first cell is the pin number and the
second cell is used to specify optional parameters (currently unused).
- interrupts : Interrupt mapping for GPIO IRQ.
- interrupt-parent : Phandle for the interrupt controller that
services interrupts for this device.
- gpio-controller : Marks the port as GPIO controller.
- compatible: "fsl,<chip>-gpio" followed by "fsl,mpc8349-gpio"
for 83xx, "fsl,mpc8572-gpio" for 85xx, or
"fsl,mpc8610-gpio" for 86xx.
- #gpio-cells: Should be two. The first cell is the pin number
and the second cell is used to specify optional
parameters (currently unused).
- interrupt-parent: Phandle for the interrupt controller that
services interrupts for this device.
- interrupts: Interrupt mapping for GPIO IRQ.
- gpio-controller: Marks the port as GPIO controller.

Optional properties:
- interrupt-controller: Empty boolean property which marks the GPIO
module as an IRQ controller.
- #interrupt-cells: Should be two. Defines the number of integer
cells required to specify an interrupt within
this interrupt controller. The first cell
defines the pin number, the second cell
defines additional flags (trigger type,
trigger polarity). Note that the available
set of trigger conditions supported by the
GPIO module depends on the actual SoC.

Example of gpio-controller nodes for a MPC8347 SoC:

gpio1: gpio-controller@c00 {
#gpio-cells = <2>;
compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
reg = <0xc00 0x100>;
interrupts = <74 0x8>;
interrupt-parent = <&ipic>;
interrupts = <74 0x8>;
gpio-controller;
interrupt-controller;
#interrupt-cells = <2>;
};

gpio2: gpio-controller@d00 {
#gpio-cells = <2>;
compatible = "fsl,mpc8347-gpio", "fsl,mpc8349-gpio";
reg = <0xd00 0x100>;
interrupts = <75 0x8>;
interrupt-parent = <&ipic>;
interrupts = <75 0x8>;
gpio-controller;
};

See booting-without-of.txt for details of how to specify GPIO
information for devices.

To use GPIO pins as interrupt sources for peripherals, specify the
GPIO controller as the interrupt parent and define GPIO number +
trigger mode using the interrupts property, which is defined like
this:

interrupts = <number trigger>, where:
- number: GPIO pin (0..31)
- trigger: trigger mode:
2 = trigger on falling edge
3 = trigger on both edges

Example of device using this is:
Example of a peripheral using the GPIO module as an IRQ controller:

funkyfpga@0 {
compatible = "funky-fpga";
...
interrupts = <4 3>;
interrupt-parent = <&gpio1>;
interrupts = <4 3>;
};
