Subject: [PATCH v3 7/7] ARM: imx7d: remove Atheros AR8031 PHY fixup
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";
};
};
