| * 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. |
