How to configure the phy reset pin for imx93x

[gongyaxuan]

I want to configure phy reset pin in the device tree, but I refer to some of your documents and posts for configuration, but it doesn't work, can you tell me how to configure correctly

This is my device tree configuration

&eqos {

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_eqos>;

    phy-mode = "rgmii-id";

    phy-handle = <&ethphy1>;

    fsl,magic-packet;

    phy-reset-gpios = <&gpio3 22 GPIO_ACTIVE_HIGH>;

    phy-reset-duration = <200>;

    phy-reset-post-delay=<20>;

    status = "okay";

    mdio {

        compatible = "snps,dwmac-mdio";

        #address-cells = <1>;

        #size-cells = <0>;

        clock-frequency = <5000000>;

        // snps,reset-gpios = <&gpio3 22 GPIO_ACTIVE_HIGH>;

        ethphy1: ethernet-phy@1 {

            compatible = "ethernet-phy-ieee802.3-c22";

            reg = <4>;

            eee-broken-1000t;

            // reset-gpios = <&gpio3 22 GPIO_ACTIVE_LOW>;

            // reset-assert-us = <10000>;

            // reset-deassert-us = <20000>;

        };

    };

};

&fec {

    pinctrl-names = "default";

    pinctrl-0 = <&pinctrl_fec>;

    phy-mode = "rgmii-id";

    phy-handle = <&ethphy2>;

    fsl,magic-packet;

    phy-reset-duration = <20>;

    phy-reset-gpios = <&gpio3 24 GPIO_ACTIVE_LOW>;

    phy-reset-post-delay=<20>;

    status = "okay";

    mdio {

        compatible = "snps,dwmac-mdio";

        #address-cells = <1>;

        #size-cells = <0>;

        clock-frequency = <5000000>;

        ethphy2: ethernet-phy@2 {

            compatible = "ethernet-phy-ieee802.3-c22";

            reg = <6>;

            eee-broken-1000t;

            // reset-gpios = <&gpio3 24 GPIO_ACTIVE_LOW>;

            // reset-assert-us = <10000>;

            // reset-deassert-us = <20000>;

        };

    };

};

The fec is reset properly, but the eqos network port is not reset

Hello @gongyaxuan 

Could you please share the steps to replicate the issue?

Best regards!

I modified the driver of eqos and added the phy reset code of eqos by referring to fec
