[PATCH v3 2/4] net: fec: Allow the PHY node to be retrieved

[sbabic at denx.de]

> As we move towards driver model, it is required to let the FEC driver
> know how to properly deal with an Ethernet PHY subnode in the device tree.
> For example:
>  &fec {
>  	pinctrl-names = "default";
>  	pinctrl-0 = <&pinctrl_microsom_enet_ar8035>;
> 	phy-handle = <&phy>;
>  	phy-mode = "rgmii-id";
>  	phy-reset-duration = <2>;
>  	phy-reset-gpios = <&gpio4 15 GPIO_ACTIVE_LOW>;
>  	status = "okay";
> 	mdio {
> 		#address-cells = <1>;
> 		#size-cells = <0>;
> 		phy: ethernet-phy at 0 {
> 			reg = <0>;
> 			qca,clk-out-frequency = <125000000>;
> 		};
> 	};
>  };
> Currently the PHY node pointer is incorrectly associated with the
> Ethernel controller instead of the PHY node itself. 
> This causes the PHY properties, such as "qca,clk-out-frequency" in
> the example above to not get parsed.
> Fix this problem by populating the phy_of_node node.

Applied to u-boot-imx, master, thanks !
