Does "hisilicon,mdio" actually have a specific meaning? Is that just 
there
for legacy reasons?

hi Arnd,
"hisilicon,mdio" is  the gernerical configuation compatible  for the 
default hisilicon chip,
We use generic hisilicon since our MDIO/PHY is same across flavour of 
SoCs.

Hi Arnd,
Yes, "hisilicon,mdio" exists for the legacy reasons to support older SoC 
Hip04.

Salil
