  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.
