Convert the Xilinx GMII to RGMII Converter device tree binding
documentation to json schema.
This converter is usually used as gem <---> gmii2rgmii <---> external phy
and, it's phy-handle should point to the phandle of the external phy.

-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>;
- };
- };
