1 APM X-Gene Standby GPIO controller bindings
3 This is a gpio controller in the standby domain.
5 There are 20 GPIO pins from 0..21. There is no GPIO_DS14 or GPIO_DS15,
6 only GPIO_DS8..GPIO_DS13 support interrupts. The IRQ mapping
7 is currently 1-to-1 on interrupts 0x28 thru 0x2d.
10 - compatible: "apm,xgene-gpio-sb" for the X-Gene Standby GPIO controller
11 - reg: Physical base address and size of the controller's registers
12 - #gpio-cells: Should be two.
13 - first cell is the pin number
14 - second cell is used to specify the gpio polarity:
17 - gpio-controller: Marks the device node as a GPIO controller.
18 - interrupts: Shall contain exactly 6 interrupts.
