Subject: [PATCH v5 09/14] net: phy: make sure MDIO bus is probed if we search for the PHY
Date: Wed, 13 Apr 2022 10:22:00 +0200	[thread overview]
Message-ID: <20220413082205.429509-10-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20220413082205.429509-1-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.
