Going from always handling qos to allowing to just wait a specific time needs explanation and is not part of "just" adding rk3576 support.

The whole delay thing is not part of the dt-binding which would be more critical to get right in the first round. So as long as your "add rk3576 support" patch really only adds the rk3576-specific data, but does not change how the shared code behaves, we should be fine and can find out about that delay later.

Right, but if you modified it, then why not be a co-author? IMO the [] is only suitable for when patches are modified between submission and application by a maintainer and that anything else should be noted under the --- line. If you feel like the difference to the vendor kernel is worth having in the git history, it should be described in the commit message itself and the reason should be meaningful (like the numbers changed incompatibly) rather than that you did the minimum required for a patch to be acceptable.
