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"; }; }; Signed-off-by: Oleksij Rempel <o.rempel@pengutronix.de> --- arch/arm/mach-imx/mach-imx7d.c | 22 ---------------------- 1 file changed, 22 deletions(-)
