-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@...0 {

+description:
+ This I2C controller is an FSI CFAM engine, providing access to a number of
+ I2C busses. Therefore this node will always be a child of an FSI CFAM node;
+ see fsi.txt for details on FSI slave and CFAM nodes.
