This sounds like a separate fix, clk_branch_ops seems to only concern
10+yo chips.

Sure, will split this patch and push the next series.

One more nit, I noticed that a lot of QUIC folks respond to the comments
to their revision-N and send revision-(N+1) like 5 seconds later..

This maybe does not concern this message, as all you did is said "ok willfix",
but if you have some sort of a company-wide "upstream best practices" board,
you may add something like "wait a bit to let others respond to your email"
