[PATCH v3 0/3] Add initial support for MAXIM 77686 mfd chip

[Jonghwa Lee]

This patchset adds support for MAX77686 which is a multifunction device including
regulator and rtc. It also includes drivers supporting rtc and regulator.
All drivers are based on MAX8997 driver and use regmap to access to registers.
To manage IRQs occured by max77686, It supports IRQ domain.

v3:
Changes in mfd core:
- Remove APIs accessing to register ( e.g. max77686_read_reg() )
  to use regmap's API directly over all related drivers.

Changes in regulator driver:
- Convert get_voltage to get_voltage_sel
- Convert set_voltage to set_voltage_sel
- Implement set_voltage_time_sel
- Register regulators unconditionally
- kzalloc -> devm_kzalloc
- Remove unneccessary printk
- Keep probing whether pdata exists or not
- Use regmap API to access to PMIC register.

Changes in rtc driver:
- Use regmap API to access to RTC register.

This patch set is tested on TRATS boards.
