That sounds indeed useful for this case. How'd the following interface
sound for the register offset / selector-to-register-value conversion?
The I2C address would be a bit trickier to get as it would touch the
regmap stuff as well, but perhaps it would be a good idea to have a
phandle to the I2C device itself, and then parse the reg field for
the address.

This looks fine, can you submit properly please?  For the I2C address
why not just have an interface to get the regmap and then provide a way
to get the underlying device back from the regmap?
