... which would have the effect that if the DTS and mvneta changes
are merged ahead of the PHY changes into Linus' tree, mvneta breaks.
Breaking stuff in the merge window is something that needs to be
avoided - that's the exact time that bisects need to work.

Splitting a dependent patch series up for different subsystems to
avoid conflicts is not always a good idea.

Linus has said many times that he's okay dealing with simple
conflicts during the merge window (normally wanting the requester to
at least be aware of the conflict.)  Yet, some seem to have fostered
an idea that "conflicts are bad and must be avoided at all costs".
I've sent Linus several pull requests with conflicts during the age
of git, and the conflict resolution diff in the pull request email.
It's *never* been a problem, even if Linus has decided a slightly
different resolution is better.
