From 721bbd4a06e83995ac1679d9cdca19a608fb0122 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Tue, 15 Mar 2011 21:17:43 +0900 Subject: ARM: EXYNOS4: Add support for gpio interrupts This patch adds support for gpio interrupts on Samsung EXYNOS4 platform. Common s5p-gpioint.c code is used for handling gpio interrupts. Each gpio line that needs gpio interrupt support must be later registered with s5p_register_gpio_interrupt() function.
