1 * Oxford Semiconductor OXNAS SoC GPIO Controller
3 Please refer to gpio.txt for generic information regarding GPIO bindings.
6 - compatible: "oxsemi,ox810se-gpio" or "oxsemi,ox820-gpio"
7 - reg: Base address and length for the device.
8 - interrupts: The port interrupt shared by all pins.
9 - gpio-controller: Marks the port as GPIO controller.
10 - #gpio-cells: Two. The first cell is the pin number and
11 the second cell is used to specify the gpio polarity as defined in
12 defined in <dt-bindings/gpio/gpio.h>:
15 - interrupt-controller: Marks the device node as an interrupt controller.
16 - #interrupt-cells: Two. The first cell is the GPIO number and second cell
17 is used to specify the trigger type as defined in
18 <dt-bindings/interrupt-controller/irq.h>:
22 - gpio-ranges: Interaction with the PINCTRL subsystem, it also specifies the
23 gpio base and count, should be in the format of numeric-gpio-range as
24 specified in the gpio.txt file.
