[PATCH net-next v2 4/6] net: mdio: scan bus based on bus capabilities for C22 and C45

From: Michael Walle
Date: Wed Jan 18 2023 - 05:56:14 EST


From: Andrew Lunn <andrew@xxxxxxx>

Now that all MDIO bus drivers which set probe_capabilities to
MDIOBUS_C22_C45 have been converted to use the name API for C45
transactions, perform the scanning of the bus based on which methods
the bus provides.
