SubjectRe: [PATCH net-next v2 0/2] of: mdio: Fall back to mdiobus_register() with NULL device_node
Hi Florian,

Thanks for your series!
I like the effect on simplifying drivers.

IMHO the CONFIG_OF=n behavior of of_mdiobus_register() (which I wasn't
aware of) is inconsistent with the behavior of other of_*() functions,
which are just empty stubs.

So I'm wondering if you should do it the other way around, and let
mdiobus_register() call of_mdiobus_register() if dev->of_node exists?

This does mean mdiobus_register() should gain a struct device * parameter,
and thus changes to many more drivers are needed.

I haven't looked at the ACPI handling, but perhaps this can be moved
inside mdiobus_register() as well?
