* This driver is based on max8998.h
|
|
*
|
|
* 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.
