I got it working with the follwing device tree setup and after reading this http://lists.infradead.org/pipermail/linux-arm-kernel/2015-January/314706.html &mac0 { phy-mode = "rmii"; phy-handle = <ðphy0>; pinctrl-names = "default"; pinctrl-0 = <&mac0_pins_a>; phy-reset-gpios = <&gpio4 13 0>; phy-reset-duration = <100>; status = "okay"; mdio { #address-cells = <1>; #size-cells = <0>; ethphy0: ethernet-phy@1 { reg = <1>; }; ethphy1: ethernet-phy@3 { reg = <3>; }; }; }; &mac1 { phy-mode = "rmii"; phy-handle = <ðphy1>; pinctrl-names = "default"; pinctrl-0 = <&mac1_pins_a>; status = "okay"; }; Thx for stub me in right direction.
