This is just one example of something that might come up and need
fitting in to the regulator API which is substantially different to the
needs of the core regulator applications.  As I keep saying I'm just not
seeing much more overlap here with the regulator API than I do with the
clock API: it feels like you've got another use case which needs an API
with a similar structure and the reference counted enable and disable
calls but otherwise very little overlap.

I don't think the enable and disable calls are enough of an overlap to
mean that the regulator use case and the operating point use case are
going to overlap well, it feels like it'd cause pain trying to match the
concepts between the two APIs.
