* MAX8997 has PMIC , MUIC , HAPTIC , RTC , FLASH , and Fuel Gauge devices .
* Except Fuel Gauge , every device shares the same I2C bus and included in
* this mfd driver . Although the fuel gauge is included in the chip , it is
* excluded from the driver because a ) it has a different I2C bus from
* others and b ) it can be enabled simply by using MAX17042 driver .
