Please double-check whether 1 is the correct address for the KSZ8051 Ethernet PHY as per your schematics.
Are there external pull-up/pull-down resistors for strapping the various configuration pins for the PHY? Or are the pull-up/pull-down provided by the i.MX7D pins?
If there are no external pull-ups, please make sure to configure the pinctrl_enet1 accordingly, so that the Ethernet PHY address can be properly configured and then mdio_bus driver can find it at the correct address.
Please check in arch/arm/boot/dts/imx6qdl-sr-som.dtsi for an example on how to configure the Ethernet PHY pin strapping via iMX IOMUX.
