+XILINX GMIITORGMII Converter Driver Device Tree Bindings
+--------------------------------------------------------
+
+The Gigabit Media Independent Interface (GMII) to Reduced Gigabit
+Media Independent Interface (RGMII) core provides the RGMII between
+RGMII-compliant Ethernet physical media devices (PHY) and the Gigabit

Ethernet controller.

quoted

+This core can be used in all three modes of operation(10/100/1000 Mb/s).
+The Management Data Input/Output (MDIO) interface is used to
+configure the Speed of operation. This core can switch dynamically
+between the three Different speed modes by configuring the conveter

register through mdio write.

quoted

+
+The MDIO is a bus to which the PHY devices are connected.  For each
+device that exists on this bus, a child node should be created.  See
+the definition of the PHY node in booting-without-of.txt for an
+example of how to define a PHY.
+
+This converter sits between the MAC and the external phy.
+MAC <==> GMII2RGMII <==> RGMII_PHY
+
+Required properties:
+  - compatible : Should be "xlnx,gmii-to-rgmii-1.0"
+  - reg : The ID number for the phy, usually a small integer
+  - phy-handle: Should point to the external phy device.
+		See ethernet.txt file in the same directory.
+
+Example:
+	mdio {
+                #address-cells = <1>;
+                #size-cells = <0>;
+		phy: ethernet-phy@0 {
+			......
+		};
+                gmiitorgmii: gmiitorgmii@8 {
+                        compatible = "xlnx,gmii-to-rgmii-1.0";
+                        reg = <8>;
+			phy-handle = <&phy>;
+                };

Indentation in this example is quite weird. You are mixing tabs and spaces.

Sure will fix in the next version...

Regards,
Kedar.

Thanks,
Michal
