Any reason to not have clock-names? I'd prefer to have them because then
we can easily hook up providers with their parents based on strings. I
suppose we'll have to support both modes of strings and numbers for
connections, but that may be more for legacy reasons that could be
avoided here if a clock-names property existed.

Not really, I did not bother because there was only one input clock.
I can easily fix this
