There are actually 2 registers (on some of them),
anatop-reg-offset, and anatop-delay-reg-offset...
Converting those to use reg and deprecating the anatop specific
items would seem like a Good Thing (tm) to me.
...wandering into less safe territory:
I know reg is usually a memory offset in bytes, but
each of the anatop memory offsets also include a bit-shift
and a bit-width item, which really narrowly defines the
register bits that pertain to each regulator.
would it be totally inappropriate to use
#address-cells = 2 and
#size-cells =1
where address cells would contain the byte offset and the bit shift, and
the size cell would contain the bit offset?
