2. It has different register address.
   We need a register-layout/configuration structure. The logic is the
same except few differences (e.g. presence of MAX77802_RTC_AE1).

Depending on what the differences are either just some variables in the
driver data that get set on probe with the different registers (if it's
just the register) or using regmap_field (if things get shifted as well,
or if it happens to make more sense) should work.

Thanks for the hints!

The addresses for registers are indeed shifted. It is non-linear because
apart of different offset at beginning, a new field appears. Anyway it
would be good for me (or other person doing this work) to get more
knowledge of what regmap API provides.
