+Device-tree bindings for FSI-attached I2C master and busses
+-----------------------------------------------------------
+
+Required properties:
+ - compatible = "ibm,i2c-fsi";
+ - reg = < address size >; : The FSI CFAM address and address
+ space size.
+ - #address-cells = <1>; : Number of address cells in child
+ nodes.
+ - #size-cells = <0>; : Number of size cells in child nodes.
+ - child nodes : Nodes to describe busses off the I2C
+ master.
+
+Child node required properties:
+ - reg = < port number > : The port number on the I2C master.
+
+Child node optional properties:
+ - child nodes : Nodes to describe devices on the I2C
+ bus.
+
+Examples:
+
+ i2c@1800 {
+ compatible = "ibm,i2c-fsi";
+ reg = < 0x1800 0x400 >;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ i2c-bus@0 {
+ reg = <0>;
+ };
+
+ i2c-bus@1 {
+ reg = <1>;
+
+ eeprom@50 {
+ compatible = "vendor,dev-name";
+ };
+ };
+ };
