Date: Mon, 28 Mar 2022 20:32:35 +0800 From: Andy Chiu <andy.chiu@...ive.com> To: radhey.shyam.pandey@...inx.com, robert.hancock@...ian.com, michal.simek@...inx.com, andrew@...n.ch Cc: davem@...emloft.net, kuba@...nel.org, pabeni@...hat.com, robh+dt@...nel.org, linux@...linux.org.uk, netdev@...r.kernel.org, devicetree@...r.kernel.org, robh@...nel.org, Andy Chiu <andy.chiu@...ive.com>, Greentime Hu <greentime.hu@...ive.com> Subject: [PATCH v6 net 1/4] net: axienet: setup mdio unconditionally The call to axienet_mdio_setup should not depend on whether "phy-node" pressents on the DT. Besides, since `lp->phy_node` is used if PHY is in SGMII or 100Base-X modes, move it into the if statement. And the next patch will remove `lp->phy_node` from driver's private structure and do an of_node_put on it right away after use since it is not used elsewhere.
