Thanks for the review.
I have added description in cover letter, i will add here as well in next revision.> And this is hidden ABI break, no justification, no mentioning either.

If you are talking ABI break if we load old DT which may lead to crash, we have .qos_requires_clocks flag which takes care of skipping QoS if required clocks are not enabled.we have addressed this issue through https://lore.kernel.org/all/20240704125515.22194-1-quic_okukatla@quicinc.com/
