You're right about that - besides, the mentioned series will take a bit of time to
get merged in and this cleanup should not be waiting for all that time, as it's
very, very nice...
In any case, I don't think that the third patch from that series will be affected,
as it's a double-definition instance: the vppsys{0,1} are really defined in mmsys
and they're simply moving it around... The committer forgot to add the two
properties (the ones that he removed from mt8195-clock) to mediatek,mmsys.yaml,
I'll send a reply over that thread.

Anyway, yes, this series definitely supersedes patch 1 in that series, so,
I'm sorry for the noise, and:
