- reg: Should contain the register base address and size of
the pin controller.
- clocks: phandle of the clock feeding the pin controller
- gpio-controller: Marks the device node as a GPIO controller.
- gpio-ranges: Specifies the mapping between gpio controller and
pin-controller pins.
- #gpio-cells: Should be two. The first cell is the gpio pin number
and the second cell is used for optional parameters.
- interrupt-controller: Marks the device node as an interrupt controller.
- #interrupt-cells: Specifies the number of cells needed to encode an
interrupt. Shall be set to 2. The first cell
defines the interrupt number, the second encodes
the trigger flags described in
