True. But there is no node for ethernet controllers in kirkwood.dtsi
yet. It will be there with mv643xx_eth DT patches applied and that is
when the corresponding replacement patch should also be taken in.

I was just confused about your referral to the merge window, because I
guess it is up to David Miller to decide when/whether to take
mv643xx_eth patches in.
