Why would the Ethernet controller play with a supply of a phy? Best regards, Krzysztof

Why would the Ethernet controller play > with a supply of a phy? Because this is the current state. Please check the all other MACs handling the phy-supply (if supported). Some of them handling it under the mdio-node (not the phy-node) but most bindings do specify this on MAC level (e.g. FEC, DWMAC (suni, rk)). I agree that the phy sould handle this but this would be a lot more effort and since the dwmac-sun8i/rk bindings do support this on MAC level I would keep it that way. Regards, Marco

Indeed phy bindings do not allow a supply. Best regards, Krzysztof
