[PATCH V4 0/6] rtc: max77686: make max77686 rtc driver as IP driver

[Laxman Dewangan]

Based on discussion on patch series of MAX77620 when adding separate
driver for max77620 RTC, it is discussed to reuse the max77686 driver
for all CHips MAX77802, MAX77686 and MAX77620. For this, the rtc-max77686
need to make as IP driver independent of their MFD parent driver.

This series makes the rtc-max77686 as independent driver from its 
parent. Required information is passed through the device parent
which is generic and does not depends on any max77686 specific
header ifnromation.
