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";

            };

        };

    };
