In case of a MDIO switch, the registered MDIO node should be
the parent of the PHY. Otherwise of_phy_connect will fail.
Hi Corentin

Sorry, I missed this patch series. Looking at patchwork...
That's my fault, I forgot to set you in recipient like in last send.
Can you represent the MDIO mux using 

Documentation/devicetree/bindings/net/mdio-mux-mmioreg.txt

It would be better if you could reuse existing infrastructure than
invent something new.
I think we cannot use mdio-mux-mmioreg since the register for doing the switch is in middle of the "System Control" and shared with other functions.
This is why we use a sycon/regmap for selecting the MDIO.

Regards
