Fine, will do in V3.

This APIs update the selected bits based on mask. This is wrapper over 
the regmap_update_bits() to provide the interface at the Palmas register 
access.
The palmas registers are paged on different i2c address and offset. The 
i2c address and offset is decided based on base_address and offset.
This APIs does all calculation to get the correct i2c slave address and 
offset address based on argument.

Thanks for pointing me this changes. I like to add this on my follow on 
(later) patch, not on this. -- 1.7.1.1
