Chanwoo Choi 54e8827d5f mfd: sec-core: Add support for S2MPU02 device
Add support for Samsung S2MPU02 PMIC device to the MFD sec-core driver.
The S2MPU02 device includes PMIC/RTC/Clock devices.

Krzysztof Kozlowski 9549b5ff00 mfd: sec-core: Remove duplicated device type from sec_pmic_dev
The device type was stored in sec_pmic_dev state container twice:
 - unsigned long type (initialized from of_device_id or i2c_device_id)
 - int device_type (initialized as above or from board files when there
   is no DTS)

The 'type' field was never used outside of probe so it can be safely
removed.

Change also the device_type in sec_pmic_dev and sec_platform_data to
unsigned long to avoid any casts.

Krzysztof Kozlowski dc6919663f mfd: sec: Add support for S2MPS14
Add support for S2MPS14 PMIC device to the MFD sec-core driver.
The S2MPS14 is similar to S2MPS11 but it has fewer regulators, two
clocks instead of three and a little different registers layout.

Krzysztof Kozlowski 677620952a mfd: sec-irq: Use consistent S2MPS11 RTC alarm interrupt indexes
The S2MPS11 RTC has two alarms: alarm0 and alarm1 (corresponding
interrupts are named similarly). Use consistent names for interrupts to
limit possible errors.

Krzysztof Kozlowski 3e1e4a5f3a mfd/rtc: s5m: fix register updating by adding regmap for RTC
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and
add new regmap for RTC.

On S5M8767A registers were not properly updated and read due to usage of
the same regmap as the PMIC.  This could be observed in various hangs,
e.g.  in infinite loop during waiting for UDR field change.

On this chip family the RTC has different I2C address than PMIC so
additional regmap is needed.

Inderpal Singh 5e393a2227 mfd: sec: Fix reg_offset for interrupt registers
reg_offset is offset of the status/mask registers. Now, since status_base
and mask_base are pointing to corresponding first registers, reg_offset
should start from 0 otheriwse regmap_add_irq_chip will fail during probe.
