| |
This fixup configures the IO voltage and disables the SmartEEE functionality.
If this patch breaks your system, enable AT803X_PHY driver and configure the PHY by the device tree:
phy-connection-type = "rgmii-id"; ethernet-phy@X { reg = <0xX>;
qca,smarteee-tw-us-1g = <24>;
vddio-supply = <&vddh>;
vddio: vddio-regulator { regulator-name = "VDDIO"; regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; };
vddh: vddh-regulator { regulator-name = "VDDH"; }; };
