(+ whatever is needed to sort out the issues I outlined in the
 indiviual replies)

That is really just fixing existing things, and has nothing to
do with any of the prefill stuff/etc. in the rest of the series.

The prefill stuff btw seems to be completely borked in current
upstream code even; it computes things based on a completely stale
cdclk frequency (the new frequency will be computed much later).

I *think* I can reorder things sufficiently to fix that, but I really
must get https://patchwork.freedesktop.org/series/154921/ landed
first...
