Still with us in next-20160307. CC'ing stmmac maintainers.
do you remember from what revision you rebased away from, when it was still
working (as a known-good state)?

Hm, next-20160111 possibly... leaving all the 5 days and 4 days ago
changes as candidates ("stmmac: share reset function between dwmac100
and dwmac1000" .. "stmmac: Fix 'eth0: No PHY found' regression").

snps,phy-addr is not correct. Can you check it?
In the stmmac_mdio if this is not passed as parameter the bus should
be scanned and the first IDs found should select the right address.
I suppose in your box there is a real transceiver, so maybe the patch
from Gabriel is not actually necessary.
