Commit Message

Krzysztof Kozlowski Feb. 17, 2014, 8:40 a.m. UTC 
This patch prepares for adding support for S2MPS14 RTC device to the
rtc-s5m driver:
1. Renames SEC* symbols to S5M.
2. Adds 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.
