Hi Andrew,
 
As i have already mentioned that this patch is based on
https://www.spinics.net/lists/netdev/msg662173.html,
<https://www.spinics.net/lists/netdev/msg662173.html>

When MDIO bus gets registered itself along with devices on it , the
function mdiobus_register() inside of_mdiobus_register(), brings
up all the PHYs on the mdio bus and attach them to the bus with the help
of_mdiobus_link_mdiodev() inside mdiobus_scan() .
Additionally it has been discussed with the maintainers that the
mdiobus_register() function should be capable of handling both ACPI &
DTB stuff
without any change to existing implementation.
Now of_mdiobus_link_mdiodev() inside mdiobus_scan() see if the
auto-probed phy has a corresponding child in the bus node, and set the
"of_node" pointer in DT case.
But lacks to set the "fwnode" pointer in ACPI case which is resulting in
mdiobus_register() failure as an end result theoretically.

Now this patch set (changes) will attempt to fill this gap and
generalise the mdiobus_register() implementation for both ACPI & DT with
no duplicacy or redundancy.

Please reply in plain text and do not top-post, thank you.
