If you put these in the Device Tree, you can use "simple-mfd-i2c"

At least the regulator probably shouldn't be - this is just a Linux
specific grouping of devices, it's not really directly a block in the
hardware in a way that's platform independent.

I've seen (and authored) regulator support in DT before.

What's changed?  They're controlled by registers, right?

Is the problem that the registers are usually split?
