[PATCHv6 0/3] mfd: sec-core: Add support S2MPU02 PMIC device

[Chanwoo Choi]

This 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 v5:
- Remove the duplicate code about mfd_add_devices() and regmap_add_irq_chip()
- Add acked message by Lee Jones for mfd patch on patch2

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

[PATCHv6 1/3] mfd: sec-core: Add support for S2MPU02 device

[Chanwoo Choi]

Add support for Samsung S2MPU02 PMIC device to the MFD sec-core driver.
The S2MPU02 device includes PMIC/RTC/Clock devices.

[PATCHv6 2/3] regulator: s2mps11: Add support S2MPU02 regulator device

[Chanwoo Choi]

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].
