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@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.
