My understanding is the requested example in the description should not
be exactly /how/ to hook up the voltage-divider as a provider, but
instead have some words about why it is interesting to do so at all. And
those words would also make it clear that is even possible. The latter
is something which, to be honest, is perhaps not all that obvious. It
has always been totally obvious to me of course, sorry for not being
clearer when I wrote the binding...

Cheers,
Peter
