Hi,
It appears that commit e34d65696d2e 'stmmac: create of compatible mdio
bus for
stmmac driver' is causing this error on the SoCFPGA platform:
[ 1.767246] libphy: PHY stmmac-0:ffffffff not found
[ 1.772106] eth0: Could not attach to PHY
[ 1.776129] stmmac_open: Cannot attach to PHY (error: -19)
[ 1.781590] IP-Config: Failed to open eth0
[ 1.785681] IP-Config: No network devices available
Doing a revert of this commit fixes the issue. Will try to debug further.
Thanks,
Dinh

Hi all,
Same here on rockchip.
See "[PATCH] stmmac: Don't exit mdio registration when mdio subnode is
not found in the DTS"

There error is here:
[ 0.663275] socfpga-dwmac ff702000.ethernet eth0: NO MDIO subnode
It appears that his commit requires an update to DTS files, which will
subsequently break legacy DTS.
Also, this commit is only in linux-next.
