From 95fbfa14b431d4d7213b8e0e167563f7a11dd5e7 Mon Sep 17 00:00:00 2001 From: Alexandre Belloni Date: Sat, 19 May 2018 10:04:46 +0200 Subject: rtc: mxc_v2: let the core handle rtc range This RTC is a 32-bit second counter. This also solves an issue where mxc_rtc_set_alarm() can return with the lock taken.
