15  This is a part of device tree bindings for Samsung S3C/S5P/Exynos SoC pin
16  controller.
17
18  External wake-up interrupts for Samsung S3C/S5P/Exynos SoC pin controller.
19  For S3C24xx, S3C64xx, S5PV210 and Exynos4210 compatible wake-up interrupt
20  controllers, only one pin-controller device node can include external wake-up
21  interrupts child node (in other words, only one External wake-up interrupts
22  pin-controller is supported).
23  For newer controllers, multiple pin-controller device node can include
24  external wake-up interrupts child node.
25
26  See also Documentation/devicetree/bindings/pinctrl/samsung,pinctrl.yaml for
27  additional information and example.
