+Device-tree bindings for P9 SBEFIFO CFAM device
+-----------------------------------------------
+
+Required properties:
+ - compatible = "ibm,p9-sbefifo";
+ - reg = < address size >; : FSI CFAM address for the SBE engine
+ and address space size.
+ - #address-cells = <1>; : Number of address cells in child
+ nodes.
+ - #size-cells = <0>; : Number of size cells in child nodes.
+
+Optional properties:
+ - <child nodes> : Devices that are accessible through
+ the SBEFIFO. Child nodes are "opaque"
+ to the SBEFIFO; the SBEFIFO needs no
+ information about a child node other
+ than if it exists or not.
+
+Child node optional properties:
+ - compatible = "dts-name"
+ - reg = < address >; : Meaningful only for the child node
+
+Examples:
+
+ sbefifo@2400 {
+ compatible = "ibm,p9-sbefifo";
+ reg = < 0x2400 0x400 >;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ occ@1 {
+ compatible = "ibm,p9-occ";
+ reg = < 1 >;
+ };
+ };
