From 8af750e3f5ca21eaa5595a96a4cf5eaa996deed4 Mon Sep 17 00:00:00 2001 From: Hebbar Gururaja Date: Wed, 11 Sep 2013 14:24:18 -0700 Subject: drivers/rtc/rtc-omap.c: add rtc wakeup support to alarm events On some platforms (like AM33xx), a special register (RTC_IRQWAKEEN) is available to enable Alarm Wakeup feature. This register needs to be properly handled for the rtcwake to work properly. Platforms using such IP should set "ti,am3352-rtc" in rtc device dt compatibility node.
