his patchset add Samsung S2MPU02 PMIC device driver in exiting S2MPS11 PMIC
driver because S2MPU02 has a little different between S2MPU02 and S2MPS1x.
The S2MPU02 PMIC has LDO[1-28] and BUCK[1-7] regulators.
Changes from v4:
- This patchset is rebased on 'Linux 3.16-rc1'.
Changes from v3:
- Fix bug of s2mps14_regulator_set_suspend_disable()
Changes from v2:
- Change patchset name
- Remove un-necessary switch statement
- Add acked message by Mark Brown for regulator patch
- Add reviewed message by Krzysztof Kozlowski for all patchs
Changes from v1:
- Fix typo about patch description
- Use existing suspend_state variable instead of defining new variable for S2MPU02
- Remove unnecessary parameter of s2mps11_pmic_dt_parse()
- Remove unfit comment of s2mpu02.h file
- Both patch2 and patch3 should be squashed on patch2

This patch add S2MPU02 regulator device to existing S2MPS11 device driver
because of little difference between S2MPS1x and S2MPU02. The S2MPU02
regulator device includes LDO[1-28] and BUCK[1-7].

This patch add documentation for S2MPU02 PMIC device. S2MPU02 has a little
difference from S2MPS11/S2MPS14 PMIC and has LDO[1-28]/Buck[1-7].

This is a bit bonkers. Instead of passing S2MPU02, why don't you pass
a new container which holds s2mpu02_devs and s2mpu02_irq_chip, then
you won't need new mfd_add_devices() and regmap_add_irq_chip() calls
for every device you want to support.

MFD changes look good to me.

I assume we have to wait for the other patches to be ready before
applying this one?
