1 * Abilis TB10x GPIO controller
4 - compatible: Should be "abilis,tb10x-gpio"
5 - reg: Address and length of the register set for the device
6 - gpio-controller: Marks the device node as a gpio controller.
7 - #gpio-cells: Should be <2>. The first cell is the pin number and the
8 second cell is used to specify optional parameters:
9 - bit 0 specifies polarity (0 for normal, 1 for inverted).
10 - abilis,ngpio: the number of GPIO pins this driver controls.
13 - interrupt-controller: Marks the device node as an interrupt controller.
14 - #interrupt-cells: Should be <1>. Interrupts are triggered on both edges.
15 - interrupts: Defines the interrupt line connecting this GPIO controller to
16 its parent interrupt controller.
17 - interrupt-parent: Defines the parent interrupt controller.
19 GPIO ranges are specified as described in
20 Documentation/devicetree/bindings/gpio/gpio.txt
