What about "gpio-multiplexer"?

It is not good that the thing using GPIOs to do multiplexing
has take a name that seem to infer that GPIOs are being
multiplexed. Now we can't do much about that we just have
to live with it. How typical of formal languages to screw
with the semantics of natural languages and create confusion...

Bindings are etched in stone and cannot be changed.
Unless we change them anyways.
But generally we can't.

Yeah just do it if you have the time, all conversions are appreciated.
(Separate patch and work item though, don't know if you need to
mix that with this work?)

I don't know about these, tell Rob if you have issues and I might
be able to pitch in, I write a fair amount of schema too.
