Hi Joakim You appear to be using an old kernel. Take a look at: commit 95f566de0269a0c59fd6a737a147731302136429 Author: Madalin Bucur <madalin.bu...@nxp.com> Date: Tue Jan 9 14:43:34 2018 +0200 of_mdio: avoid MDIO bus removal when a PHY is missing If one of the child devices is missing the of_mdiobus_register_phy() call will return -ENODEV. When a missing device is encountered the registration of the remaining PHYs is stopped and the MDIO bus will fail to register. Propagate all errors except ENODEV to avoid it.
