      1* Oxford Semiconductor OXNAS SoC GPIO Controller
      2
      3Please refer to gpio.txt for generic information regarding GPIO bindings.
      4
      5Required properties:
      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>:
     13      0 = GPIO_ACTIVE_HIGH
     14      1 = GPIO_ACTIVE_LOW
     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>:
     19      IRQ_TYPE_EDGE_RISING
     20      IRQ_TYPE_EDGE_FALLING
     21      IRQ_TYPE_EDGE_BOTH
     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.

     33	gpio-controller;
     34	interrupt-controller;
     35	#interrupt-cells = <2>;
     36	gpio-ranges = <&pinctrl 0 0 32>;
     37};

     44		linux,code = <1>;
     45		gpios = <&gpio0 12 0>;
