Hi,

Sorry for the mess but we did this wrong.
The S2MPS13 RTC is slightly different than S2MPS14 and that difference
is important. It is embarrassing... but the difference was written
small-print as a note in datasheet. Really. I found it after carefully
comparing two PDFs. The impact of difference was not detected because
of error in DTS for Exynos5433-based board.

This patch should be dropped (or reverted) and "s2mps13-rtc" should be
used for S2MPS13 RTC mfd_cell. The RTC driver (rtc/rtxc-s5m) should
have its own support for RTC which I will add in separate patch.

Lee, once again sorry for the mess. How would you like to proceed? Can
you just drop this commit?

Best regards,
Krzysztof
