| 16 | controller. |

| 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. |
