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. | |
