4 The Gigabit Media Independent Interface (GMII) to Reduced Gigabit Media
5 Independent Interface (RGMII) core provides the RGMII between RGMII-compliant
6 Ethernet physical media devices (PHY) and the Gigabit Ethernet controller.
7 This core can be used in all three modes of operation(10/100/1000 Mb/s).
8 The Management Data Input/Output (MDIO) interface is used to configure the
9 Speed of operation. This core can switch dynamically between the three
10 Different speed modes by configuring the conveter register through mdio write.
12 This converter sits between the ethernet MAC and the external phy.
13 MAC <==> GMII2RGMII <==> RGMII_PHY
15 For more details about mdio please refer phy.txt file in the same directory.
18 - compatible : Should be "xlnx,gmii-to-rgmii-1.0"
19 - reg : The ID number for the phy, usually a small integer
20 - phy-handle : Should point to the external phy device.
21 See ethernet.txt file in the same directory.
