Here I have a question about the implementation specifically with
88pm800. this chip has 3 register pages, and 3 i2c address corresponding
to each page. so it requires an additional parameter to point out the
page(i2c) to be accessed. currently I didn't think of a good API to
export for such purpose. seems to me, the 88pm800 chip is already bound
to i2c interface, and using regmap directly is a better solution. could
you give some suggestions?

is it OK to export another two groups of r/w interface for gpadc and
power page separately in 88pm800? such as pm800_gpadc_read_reg() /
pm800_power_read_reg() etc?  Appreciate any comments.

What do you mean by pages?  regmap has paging support which just maps
everything into a single flat register map from the point of view of
callers.
