The referenced commit broke initializing macb on the EVB-KSZ9477 eval board.
There, of_mdiobus_register was called even for the fixed-link representing
the SPI-connected switch PHY, with the result that the driver attempts to
enumerate PHYs on a non-existent MDIO bus:

	libphy: MACB_mii_bus: probed
	mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
        [snip]
	mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31
	macb f0028000.ethernet: broken fixed-link specification

I added the people involved in 739de9a1563a to Cc. Maybe they want to
comment. So not stripping the remaining part of the original mail.

Thanks Uwe for Cc: in my.

Ahmed, where is the device tree for the EVB-KSZ9477?

Thanks
