Can this all be handled by the 'gpio-mux-clock' compatible/driver? I
suppose it may need an update to add the rounding policy that you want
via some sort of DT property, but otherwise it would be fine?

Hmm.. not sure.
If we can add new feature (= .round_rate ?) on gpio-mux-clock,
I can consider it.

Yes that would be the idea. Extend gpio-mux-clock driver to have what
you want with rounding. I'm not really sure why there is a rounding
policy needed though. Is it a static configuration at boot, or does the
code using this gpio clk need to search the parent rate space somehow
and mux it over?
