From 61ee93cd18c7f99236c17829d8fe65f56e8dd392 Mon Sep 17 00:00:00 2001 From: Haojian Zhuang Date: Mon, 20 Feb 2012 16:34:05 +0800 Subject: rtc: sa1100: remove periodic code Since periodic timer is already supported by hrtimer in rtc interface, we needn't keep the duplicated code in rtc-sa1100.c any more.
