From 8521420375d0e6824a76fda24677f428c1d3f598 Mon Sep 17 00:00:00 2001 From: Jonathan Kliegman Date: Thu, 4 Apr 2013 15:15:49 +0900 Subject: [PATCH] ARM: EXYNOS: Clear ENABLE_WAKEUP_SW bit when entering suspend Setting this bit to 0 causes the system to wait until suspended to use the wakeup masks. With it being set high previously, masked interrupts were being received and processed before the EINT_WAKEUP_MASK was configured.
