of: mdio: Support fixed links in of_phy_get_and_connect()
By a simple extension of of_phy_get_and_connect() drivers
that have a fixed link on e.g. RGMII can support also
fixed links, so in addition to:
ethernet-port {
phy-mode = "rgmii";
phy-handle = <&foo>;
};
This setup with a fixed-link node and no phy-handle will
now also work just fine:
ethernet-port {
phy-mode = "rgmii";
fixed-link {
speed = <1000>;
full-duplex;
pause;
};
};
This is very helpful for connecting random ethernet ports
to e.g. DSA switches that typically reside on fixed links.
The phy-mode is still there as the fixes link in this case
is still an RGMII link.
Tested on the Cortina Gemini driver with the Vitesse DSA
router chip on a fixed 1Gbit link.
