The QCC2072 patchset under internal review is already 19 patches, all of which
are specific to the ath12k driver and hence would go through ath.git.

I'd prefer to not bury this patch in that series.

Would you be happy with a commit text note that indicates this functionality
will be used in an upcoming series that adds support for QCC2072 to the ath12k
driver?
