1 Altera GPIO controller bindings
4 - compatible:
5   - "altr,pio-1.0"
6 - reg: Physical base address and length of the controller's registers.
7 - #gpio-cells : Should be 2
8   - The first cell is the gpio offset number.
9   - The second cell is reserved and is currently unused.
10 - gpio-controller : Marks the device node as a GPIO controller.
11 - interrupt-controller: Mark the device node as an interrupt controller
12 - #interrupt-cells : Should be 1. The interrupt type is fixed in the hardware.
13   - The first cell is the GPIO offset number within the GPIO controller.
14 - interrupts: Specify the interrupt.
15 - altr,interrupt-type: Specifies the interrupt trigger type the GPIO
16   hardware is synthesized. This field is required if the Altera GPIO controller
18   but hardware synthesized. Required if GPIO is used as an interrupt
19   controller. The value is defined in <dt-bindings/interrupt-controller/irq.h>
27 - altr,ngpio: Width of the GPIO bank. This defines how many pins the
28   GPIO device has. Ranges between 1-32. Optional and defaults to 32 if not
