I guess you mean
[PATCH v6 00/25] Add qemu_getrandom and ARMv8.5-RNG etc
Message-Id: <20190510173049.28171-1-richard.henderson@linaro.org>
You can make the dependency machine-readable by declaring
Based-on: <20190510173049.28171-1-richard.henderson@linaro.org>
in your cover letter. Patchew will then test your series on top of
Richard's.
