+Required properties:
+- compatible : "ibm,ndfc".
+- reg : should specify chip select and size used for the chip (0x2000).
+
+Optional properties:
+- ccr : NDFC config and control register value (default 0).
+- bank-settings : NDFC bank configuration register value (default 0).
+
+Notes:
+- partition(s) - follows the OF MTD standard for partitions
+
+Example:
+
+ndfc@1,0 {
+       compatible = "ibm,ndfc";
+       reg = <0x00000001 0x00000000 0x00002000>;
+       ccr = <0x00001000>;
+       bank-settings = <0x80002222>;
+       #address-cells = <1>;
+       #size-cells = <1>;
+
+       nand {
+               #address-cells = <1>;
+               #size-cells = <1>;
