[v1,7/7] ARM: imx7d: remove Atheros AR8031 PHY fixup

Commit Message

Oleksij Rempel Feb. 3, 2021, 9:18 a.m. UTC

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>;
		eee-broken-1000t;
		eee-broken-100tx;

		vddio-supply = <&vddh>;

		vddio: vddio-regulator {
			regulator-name = "VDDIO";
			regulator-min-microvolt = <1800000>;
			regulator-max-microvolt = <1800000>;
		};

		vddh: vddh-regulator {
			regulator-name = "VDDH";
		};
	};
