Subject: [PATCH v1 8/9] net: phy: make sure MDIO bus is probed if we search for the PHY
Date: Mon, 21 Mar 2022 10:26:05 +0100	[thread overview]
Message-ID: <20220321092606.1459834-9-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220321092606.1459834-1-o.rempel@pengutronix.de>

For DSA support we need to work with multiple MDIO buses. So, we need to
make that MDIO bus node is probed before on on request of DSA switch
registration.
