You've already joined in on the discussion for the patch "net: stmmac:
dwmac-rk: Add internal phy support". It is pretty much the same issue.
Please wait for it to come to a proper conclusion. At least then we can
agree on something so different platforms with the same problem don't
have diverging solutions.
