I answered somewhere else, but I can elaborate here as well.

The idea, yes, to have the driver in the parts:
 _core.c
 _platform.c
 _i2c.c

To achieve that, it needs first to split the driver followed by likely
conversion to regmap. With that done it may be used in i2c with a little
code added into _i2c.c.

We have examples in kernel for that.
