So above DT fix for ARC went into 4.6-rc1 and ethernet was still broken on 
axs103
board.

-->8-
libphy: PHY stmmac-0: not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)
-->8-

On 4.6-rc2 if I revert the DT change, ethernet works again.

@Giuseppe, @Phil, @Gabriel, I see you have made changes in that area. I presume
that above revert is the right/sufficient thing or do we need to do something 
else
as well.

TIA,
-Vineet

That's what happens on eth0 up:

libphy: PHY stmmac-0: not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)
--->8

Simplest solution is to add PHY description in board's .dts.
And so we do here.

hmm I think so, we pushed all the changes in net-next to fix the MDIO
initialization according to the different DT parameter settings. So
unless there is some other case to cover, I think that the best
approach is to do the revert.

pls, let me know
