 - I couldn't find a way to detect the number of regulators in the
   device tree, if we wanted to refuse to probe the device if there
   are too many regulators, which might be required for safety, see
   the thread on v2 [1].

You'd need to enumerate all the properties of the device and look
for things matching *-supply.

I see ,-) I was hoping for something slightly cleaner, or maybe an
existing function in the core.

Steven: How strongly do you feel about this? If so I can add that
check in the next revision.

Also, just a heads-up, I'm out for the next 2 weeks, I'll send v4 after that.
