Michal Vokáč f3f9dc34f2 ARM: dts: imx6dl-yapp4: Move the internal switch PHYs under the switch node ... [ Upstream commit 79978bff2e ] We identified that the PHYs actually do not work since commit 7da7b84fee ("ARM: dts: imx6dl-yapp4: Move phy reset into switch node") as a coincidence of several circumstances. The reset signal is kept asserted by a pull-down resistor on the board unless it is deasserted by GPIO from the SoC. This is to keep the switch dead until it is configured properly by the kernel and user space. Prior to the referenced commit the switch was reset by the FEC driver and the reset GPIO was actively deasserted. The mdio-bus was scanned and the attached switch and its PHYs were found and configured. With the referenced commit the switch is reset by the qca8k driver. Because of another bug in the qca8k driver, functionality of the reset pin depends on its pre-kernel configuration. See commit c44fc98f0a ("net: dsa: qca8k: fix illegal usage of GPIO") The problem did not appear until we removed support for the switch and configuration of its reset pin from the bootloader. To fix that, properly describe the internal mdio-bus configuration of the qca8334 switch. The PHYs are internal to the switch and sit on its internal mdio-bus.
