Hello all,

I'm working on a custom i.MX8DXL board in kernel version of 5.4.24. Ethernet is already worked in 5.15.52 with the same dts and board configuration. but porting back ethernet from 5.15.52 to 5.4.24 is not working.

Below is the dts file

&eqos {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_eqos>;
phy-mode = "rgmii-id";
phy-handle = <&ethphy0>;
fsl,magic-packet;
// nvmem-cells = <&fec_mac1>;
nvmem-cell-names = "mac-address";
snps,reset-gpios = <&lsio_gpio0 20 GPIO_ACTIVE_LOW>;
snps,reset-delays-us = <10 20 200000>;
status = "okay";

mdio {
compatible = "snps,dwmac-mdio";
#address-cells = <1>;
#size-cells = <0>;

ethphy0: ethernet-phy@1 {
compatible = "ethernet-phy-ieee802.3-c22";
reg = <1>;
rxdv-skew-ps = <480>;
txen-skew-ps = <480>;
rxd0-skew-ps = <480>;
rxd1-skew-ps = <480>;
rxd2-skew-ps = <480>;
rxd3-skew-ps = <480>;

txd2-skew-ps = <360>;
txd3-skew-ps = <360>;
txc-skew-ps = <1020>;
rxc-skew-ps = <960>;

};
};
};

Hi,

Thank you for your interest in NXP Semiconductor products,

You are using NXP drivers and building micrel driver, try attaching it to a micrel PHY. This may be useful.

Regards
