This looks pretty much OK however I am in general suspicious of MFDs
that have subdevices like this in the DT - it doesn't seem like this is
a reusable device which can appear anywhere else so you're pretty much
just representing the way that Linux splits things up here rather than a
reusable IP that can reasonably have a separate binding.
If you had a binding which did something like enumerate the individual
IP blocks as individual devices that'd be more interesting, I could see
for example that a different PMIC might have a different set of register
compatible regulator IPs laid out. It looks like that might be doable,
but it's in no way essential.
