I really prefer some code that is concise and clear but a little
duplicated over some code that shares every possible lines of code but
is a giant mess impossible to understand.

I just came across the reg_field stuff in regmap that would allow to
partially address that problem though, there's still the bit indices
issue to overcome though.

It's hard to tell without testing.
