[PATCH v5 0/4] mfd: sec: add S2MPS15 PMIC support

[Alim Akhtar]

Samsung's S2MPS15 PMIC is targetted to be used with Samsung's Exynos7 SoC.
The S2MPS15 PMIC is similar in functionality to S2MPS11/14 PMIC. It contains
27 LDO and 10 Buck regulators, RTC, three 32.768 KHz clock outputs and allows
programming these blocks via a I2C interface. This patch series adds initial
support for LDO/Buck regulators of S2MPS15 PMIC.

Changes since v4:
* Dorpped Krzysztof reviewed-by and Lee Acked-by tags from patch 1/4,
  because of the new changes to DT bindings. Seeking a fresh review/ack tags.
* Removed samsung,s2mps15-clk compatible as we can reuse exsisting compatible of s2mps13.
* Added acked-by on patch 2/4
* Modified rtc driver as s2mps15 differs from s2mps14/13 etc, addressed Krzysztof
  concerns on rtc patch.
  There are some other improvement suggestion from Krzystof for the rtc, I feel that can be done
  as a sperate patch later.

Changes since v3:
* Changes regulator driver name from s2mps15-pmic -> s2mps15-regulator as disscussed here [2]
* Re-use the exsisting compatible/names for s2mps15 clock block.

Changes since v2:
* Addressed Lee Jones review comments.

Changes since v1:
* Added suggestion from Krzysztof [1].
* Added s2mps15's 32.768 clocks support.
* Added s2mps15's rtc support.

V1 of these patches (with a lesser features) were posted a year back,
since then there is not much progress on this, this is my attempt to
move things forward.

This series is based on linux-next-20151022.
This is tested on exynos7-espresso board.
