Subject: [PATCH 2/2] ftgmac100: Make the MDIO bus a child of the ethernet device
Date: Mon, 24 Jul 2017 16:59:07 +1000 [thread overview]
Message-ID: <1500879547.10674.63.camel@kernel.crashing.org> (raw)
Populate mii_bus->parent with our own platform device before
registering, which makes it easier to locate the MDIO bus
in sysfs when trying to diagnose problems.
