Subject: [net-next PATCH v1 4/7] net: mdiobus: Introduce fwnode_mdiobus_register_phy()
Date: Wed, 30 Sep 2020 21:34:27 +0530 [thread overview]
Message-ID: <20200930160430.7908-5-calvin.johnson@oss.nxp.com> (raw)
In-Reply-To: <20200930160430.7908-1-calvin.johnson@oss.nxp.com>
Introduce fwnode_mdiobus_register_phy() to register PHYs on the
mdiobus. From the compatible string, identify whether the PHY is
c45 and based on this create a PHY device instance which is
registered on the mdiobus.
