I'm in the process of finalizing the pull requests for 5.16, this came
up since you
have soc@xxxxxxxxxx on Cc, but it looks like you don't have an Ack for the
clock driver, and I have not heard from Shawn or Sasha about whether they
want to pick it up in a separate branch or I should pick it up.

I suggest we leave it for this time then, let's plan for 5.18 instead.
