mfd: MAX8997/8966 support
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).

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.
