From 13b18c20952d0a096a80e3c30bbb68022f4d9eb7 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 17 May 2014 23:19:20 +1000 Subject: [PATCH] mfd/rtc: sec/s5m: rename SEC* symbols to S5M Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver: 1. Rename SEC* symbols to S5M. 2. Add S5M prefix to some of defines which are different between S5M876X and S2MPS14. This is only a rename-like patch, new code is not added.
