Subject: [PATCH v2 8/8] mfd: max77658: Add ADI MAX77643/54/58/59 MFD Support

MFD driver for MAX77643/MAX77654/MAX77658/MAX77659 to enable its sub
devices.

The MAX77643 is a multi-function devices. It includes
regulator.

The MAX77654 is a multi-function devices. It includes
regulator and charger.

The MAX77658 is a multi-function devices. It includes
regulator, charger and battery.

The MAX77659 is a multi-function devices. It includes
regulator and charger.
