[Alim Akhtar]

Hi Lee/Mark,

This a resend of series [0] that adds s2mps15 pmic support.
These patches have no changes, just collected some Reviewed-by and Acked-by tags.
[0] -> https://lkml.org/lkml/2015/10/30/44

Mark,
Can I have you acked-by for patch# 2/3? so that these can go in via MFD tree.

[RESEND PATCH v5 1/3] mfd: sec: Add support for S2MPS15 PMIC

[Alim Akhtar]

From: Thomas Abraham <thomas.ab@samsung.com>

Add support for S2MPS15 PMIC which is similar to S2MPS11 PMIC. The S2MPS15
PMIC supports 27 LDO regulators, 10 buck regulators, RTC, three 32.768KHz
clock outputs and battery charger. This patch adds initial support for
LDO and buck regulators of S2MPS15 device.

[rtc-linux] [RESEND PATCH v5 2/3] regulator: s2mps11: add support for S2MPS15 regulators

[Alim Akhtar]

From: Thomas Abraham <thomas.ab@samsung.com>

The S2MPS15 PMIC is similar in functionality to S2MPS11/14 PMIC. It contains
27 LDO and 10 Buck regulators and allows programming these regulators via a
I2C interface. This patch adds initial support for LDO/Buck regulators of
S2MPS15 PMIC.

[rtc-linux] [RESEND PATCH v5 3/3] drivers/rtc/rtc-s5m.c: add support for S2MPS15 RTC

[Alim Akhtar]

RTC found in s2mps15 is almost same as one found on s2mps13
with few differences in RTC_UPDATE register fields, like:
1> Bit[4] and Bit[1] are reversed
   - On s2mps13
          WUDR -> bit[4], AUDR -> bit[1]
   - On s2mps15
	  WUDR -> bit[1], AUDR -> bit[4]
2> In case of s2mps13, for alarm register, need to set both
   WDUR and ADUR high, whereas for s2mps15 only set AUDR to high.
3> On s2mps15, WUDR, RUDR and AUDR functions should never be used
   at the same time.

This patch add required changes to enable s2mps15 rtc timer.
