  21  * This driver is based on max8998.h
  22  *
  23  * MAX8997 has PMIC, MUIC, HAPTIC, RTC, FLASH, and Fuel Gauge devices.
  24  * Except Fuel Gauge, every device shares the same I2C bus and included in
  25  * this mfd driver. Although the fuel gauge is included in the chip, it is
  26  * excluded from the driver because a) it has a different I2C bus from
  27  * others and b) it can be enabled simply by using MAX17042 driver.
