So the same piece of hardware is modeled differently twice?
i.e. the same GDSCs are reached once with register accesses and once
registered as "Q6 vote clocks"?
that sounds like a bit of an overstep to register them with genpd and CCF
depending on what entity controls them.. perhaps the "q6 vote clocks" could
be remodeled as power domains as that's what they're ultimately seem to
be referencing.. Krzysztof should have an opinion.
