What does this mean exactly? The interconnect .sync_state() is
responsible to drop the initial maximum bandwidth votes, with the
assumption that all active devices have voted for the bandwidth they
need. How does this relate to "requiring interface clocks"?

Doesn't this make everything painfully slow? There are no interconnect
consumers at all in qcm2290.dtsi. I would expect that all bandwidths
end up at minimum.

Thanks,
