You can rebase ahead of time and add "Based-on: <message-id>" to the
cover letter so the maintainer knows there is a dependency between the
patch series.

https://www.qemu.org/docs/master/devel/submitting-a-patch.html#id35

When sending the series that depends on another series, be careful to
specify only the commit range from the end of the other series so that
you don't include all the commits from the other series. That way
reviewers aren't distracted by a bunch of other commits that are not
part of this series.

Summarizing:
1. Rebase your other series on this one.
2. Carefully send a new revision of your other series with only its
   commits (not the commits from this series) and add "Based-on:
   <message-id>" referencing this patch series by its Message-Id.
