here is my device tree setting (derived from imx28-evk.dts):
&mac0 {
phy-mode = "rmii";
pinctrl-names = "default";
pinctrl-0 = <&mac0_pins_a>;
phy-reset-gpios = <&gpio4 13 0>;
phy-reset-duration = <100>;
status = "okay";
};
&mac1 {
phy-mode = "rmii";
pinctrl-names = "default";
pinctrl-0 = <&mac1_pins_a>;
status = "okay";
};
Best Regards,
Oliver
