+description: |
+  This binding describes an FSI CFAM engine called the FSI2SPI. Therefore this
+  node will always be a child of an FSI CFAM node; see fsi.txt for details on
+  FSI slave and CFAM nodes. This FSI2SPI engine provides access to a number of
+  SPI controllers.
+
+properties:
+  compatible:
+    enum:
+      - ibm,fsi2spi

+  reg:
+    items:
+      - description: FSI slave address
+
+required:
+  - compatible
+  - reg
+
+examples:

+    fsi2spi@...0 {
+        compatible = "ibm,fsi2spi";
+        reg = <0x1c00 0x400>;
