1 Avionic Design N-bit GPIO expander bindings
4 - compatible: should be "ad,gpio-adnp"
5 - reg: The I2C slave address for this device.
6 - interrupts: Interrupt specifier for the controllers interrupt.
7 - #gpio-cells: Should be 2. The first cell is the GPIO number and the
9   - bit 0: polarity (0: normal, 1: inverted)
10 - gpio-controller: Marks the device as a GPIO controller
11 - nr-gpios: The number of pins supported by the controller.
