As Angelo provided additional clarification in [15/16], explaining that
certain conditions in [2/16] and [3/16] were intentionally omitted due
to the need to integrate the same IP with different operations.
Apologies for any inconvenience this has caused you.

Upon examining the minor hardware changes in MDP for MT8183 and MT8195
RDMA ([3/16]), it appears that branching cannot be avoided. However,
consolidating these changes has the additional advantage of addressing
Rob's concerns from v4. Perhaps we can consider the current changes as
a form of progress.
