This should be fixed by some work done some days

Pls see "stmmac: MDIO fixes" patch-set and let me know
if ok on your side.
Yes, that works for me.

Since commit 88f8b1bb41c6 ("stmmac: Fix 'eth0: No PHY found'
regression") we no longer allocate mdio_bus_data unless there is a MDIO
subnode. This breaks the ethernet on the Radxa Rock2 (using
rk3288-rock2-square.dts) which does not have an MDIO subnode.
That commit was correct that the phy_bus_name test is unhelpful since we
allocate "plat" in the same function and never set phy_bus_name so let's
just drop the test which restores the previous behaviour.
