Subject: [net-next PATCH v2 04/14] net: phy: Introduce fwnode_get_phy_id()
Date: Tue, 15 Dec 2020 22:13:05 +0530 [thread overview]
Message-ID: <20201215164315.3666-5-calvin.johnson@oss.nxp.com> (raw)
In-Reply-To: <20201215164315.3666-1-calvin.johnson@oss.nxp.com>
Extract phy_id from compatible string. This will be used by
fwnode_mdiobus_register_phy() to create phy device using the
phy_id.
