Why do you require one single Regmap anyway?  Are they register banks
not neatly separated on a per-function basis?

AFAIK you can only have one I2C device driver per device, hence the
simple-mfd-i2c.

Sorry, can you provide more detail.

I'd still like further explanation to be sure, but if you mean what I
think you mean then, no, I don't think that's correct.

We've already discussed this:

And how would a device tree binding look like if you have multiple
i2c devices with the same i2c address?
