1 Binding for Qualcomm Atheros AR7xxx/AR9xxx GPIO controller
4 - compatible: has to be "qca,<soctype>-gpio" and one of the following
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
11 second cell is used to specify optional parameters.
12 - ngpios: Should be set to the number of GPIOs available on the SoC.
15 - interrupt-parent: phandle of the parent interrupt controller.
16 - interrupts: Interrupt specifier for the controllers interrupt.
17 - interrupt-controller : Identifies the node as an interrupt controller
18 - #interrupt-cells : Specifies the number of cells needed to encode interrupt
