Subject[Patch v1 1/7] DA9055 MFD core driver
From
Date
This is the DA9055 MFD core driver that instantiate all the dependent
component
drivers and provides them the device access via I2C.

This patch is functionally tested on Samsung SMDK6410.

+ Say yes here for support of Dialog Semiconductor DA9055. This is
