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.
I'm not that strongly bothered about it - my only worry is that there
may be hardware out there that might be broken by not activating a
regulator. But I don't know how common this multi-regulator design is in
practise.
Thanks,
Steve
Also, just a heads-up, I'm out for the next 2 weeks, I'll send v4 after that.
