Hello NXP team,
We are using MV88E6341 switch connceted to fec2 in our custom carrier card. We are unable to access the MDIO bus with fixed-link node in device tree.
We can able to access the MDIO bus without fixed-link node in DTS but fec2 link is down.
Please suggest us to fix this.
My DTS file contents are pasted below,
&fec2 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_enet2>;
//phy-handle = <&switchphy0>;
phy-mode = "rgmii";
fsl,magic-packet;
#if 1
fixed-link {
speed=<1000>;
full-duplex;
};
#endif
#if 1
mdio_bus: mdio {
#address-cells = <1>;
#size-cells = <0>;
reg = <3>;
switch: switch@3 {
compatible = "marvell,mv88e6085";
#address-cells = <1>;
#size-cells = <0>;
reg = <3>;
dsa,member = <0 0>;
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
label = "p0";
phy-mode = "rgmii";
ethernet = <&fec2>;
//phy-handle = <&switchphy0>;
fixed-link {

full-duplex;
};

port@1 {

};
port@3 {

phy-handle = <&switchphy3>;
};
port@4 {

label = "p4";
phy-handle = <&switchphy4>;
};
};
mdio {
#address-cells = <1>;
