791 * the wakeup interrupt support, then the setting up external wakeup
792 * interrupts here can be skipped. This check here is temporary to
793 * allow exynos4 platforms that do not use Samsung pinctrl driver to
794 * co-exist with platforms that do. When all of the Samsung Exynos4
795 * platforms switch over to using the pinctrl driver, the wakeup
796 * interrupt support code here can be completely removed.
