 Required properties:
 
- - reg:                The CS line the peripheral is connected to
+ - compatible: "ti,omap2-nand"
+ - reg:                range id (CS number), base offset and length of the
+               NAND I/O space
+ - interrupt-parent: must point to gpmc node
+ - interrupts: Two interrupt specifiers, one for fifoevent, one for termcount.
