Yes, this is exactly the sort of change I'm talking about above.  We
need to take a better decision about deciding to use regmap for the
device I/O, this seems like a useful input.  Checking for ops should be
even better, though - one could potentially use regmap but want to wrap
it for some reason (can't think of one right now though).

What I *don't* think is a good idea is trying to bodge this in the I/O
code.
