 * This driver is based on max77686.h
 *
 * MAX77686 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.
