From cafa1d8b0c90252e73f20db1b6f32cf88e73ff17 Mon Sep 17 00:00:00 2001 From: Matti Halme Date: Thu, 15 Jan 2009 13:50:56 -0800 Subject: [PATCH] rtc: rtc-twl4030 don't mask alarm interrupts on shutdown A triggering RTC alarm should be able to power on a device that has been powered off. This patch enables that on twl4030 by not masking the alarm interrupt at shutdown.
