+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.
+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.
+
+This converter sits between the ethernet MAC and the external phy.
+MAC <==> GMII2RGMII <==> RGMII_PHY
+
+For more details about mdio please refer phy.txt file in the same directory.
+
+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>;
+ };
+ };
