From b5f09df246a8a24a3b4acb669cbf95d2a063176b Mon Sep 17 00:00:00 2001 From: Marek Vasut Date: Sun, 17 Jan 2021 00:16:16 +0100 Subject: [PATCH] net: phy: micrel: Try default PHY ofnode first The phydev structure has a PHY OF node pointer in it, use that OF node first when looking up PHY OF node properties, since that is likely the correct PHY OF node pointer. If the pointer is not valid, which is the case e.g. on legacy DTs, fall back to parsing MAC ethernet-phy subnode.
