4 - compatible: has to be "qca,<soctype>-gpio" and one of the following
6   - "qca,ar7100-gpio"
7   - "qca,ar9340-gpio"
8 - reg: Base address and size of the controllers memory area
9 - gpio-controller : Marks the device node as a GPIO controller.
10 - #gpio-cells : Should be two. The first cell is the pin number and the
12 - ngpios: Should be set to the number of GPIOs available on the SoC.
15 - interrupts: Interrupt specifier for the controllers interrupt.
16 - interrupt-controller : Identifies the node as an interrupt controller
17 - #interrupt-cells : Specifies the number of cells needed to encode interrupt
