Possibly...  it's mostly a function of what the consumers of the
functionality look like - if that code looks weird calling into the
regulator API then it's bad, if that code looks OK it's fine.  I haven't
looked at the hardware at all so don't have strong feelings either way
so long as the result looks tasteful.
