1Device-tree bindings for FSI-attached I2C master and busses
2-----------------------------------------------------------

4Required properties:
5 - compatible = "ibm,i2c-fsi";
6 - reg = < address size >;		: The FSI CFAM address and address
7					  space size.
8 - #address-cells = <1>;		: Number of address cells in child
9					  nodes.
10 - #size-cells = <0>;			: Number of size cells in child nodes.
11 - child nodes				: Nodes to describe busses off the I2C
12					  master.
13
14Child node required properties:
15 - reg = < port number >		: The port number on the I2C master.
16
17Child node optional properties:
18 - child nodes				: Nodes to describe devices on the I2C
19					  bus.
