commit e34d65696d2e broke stmmac ethernet on socfpga
Subsystems (2)
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.

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.
