MAX8997/MAX8966 chip is a multi-function device with I2C bussses. The chip includes PMIC, RTC, Fuel Gauge, MUIC, Haptic, Flash control, and Battery (charging) control. This patch is an initial release of a MAX8997/8966 driver that supports to enable the chip with its primary I2C bus that connects every device mentioned above except for Fuel Gauge, which uses another I2C bus. The fuel gauge is not supported by this mfd driver and is supported by a seperated driver of MAX17042 Fuel Gauge (yes, the fuel gauge part is compatible with MAX17042).
