+* Cavium NAND controller
+
+Required properties:
+
+- compatible:		should be "cavium,cn8xxx-nand"
+- reg:			PCI devfn
+- clocks:		must contain system clock
+- #address-cells:	<1>
+- #size-cells:		<0>
+
+The nand flash controller may contain up to 8 subnodes representing
+NAND flash chips. Their properties are as follows.
+
+Required properties:
+- compatible:		should be "cavium,nandcs"
+- reg:			a single integer representing the chip-select number
+- nand-ecc-mode:	see nand.txt
+
+Example:
+
+nfc: nand at b,0 {
+	compatible = "cavium,cn8xxx-nand";
+	reg = <0x5800 0 0 0 0>;
+	clocks = <&sclk>;
+	#address-cells = <1>;
+	#size-cells = <0>;
+
+	nand at 1 {
+		compatible = "cavium,nandcs";
+		reg = <1>;
+		nand-ecc-mode = "on-die";
+};
