I don't see any particular problem with this? I mean we pretty surely
have the x4 clock on the H6, and for the H616 the manual agrees to your
findings?

I don't see good reasons to introduce undocumented and useless clocks at
this point.
So I will leave this out unless someone protests.

It's not in the manual (which is what I look at). Not sure I can trust
the vendor kernel more here.
