* Samsung S3C2410 and compatible NAND flash controller

Required properties:
- compatible : The possible values are:
	"samsung,s3c2410-nand"
	"samsung,s3c2412-nand"
	"samsung,s3c2440-nand"
- reg : register's location and length.
- #address-cells, #size-cells : see nand-controller.yaml
- clocks : phandle to the nand controller clock
- clock-names : must contain "nand"

Optional child nodes:
Child nodes representing the available nand chips.

Optional child properties:
- nand-ecc-mode : see nand-controller.yaml
- nand-on-flash-bbt : see nand-controller.yaml

Each child device node may optionally contain a 'partitions' sub-node,
which further contains sub-nodes describing the flash partition mapping.
See mtd.yaml for more detail.

Example:

nand-controller@4e000000 {
	compatible = "samsung,s3c2440-nand";
	reg = <0x4e000000 0x40>;

	#address-cells = <1>;
        #size-cells = <0>;

	clocks = <&clocks HCLK_NAND>;
	clock-names = "nand";

	nand {
		nand-ecc-mode = "soft";
		nand-on-flash-bbt;

		partitions {
			compatible = "fixed-partitions";
			#address-cells = <1>;
			#size-cells = <1>;

			partition@0 {
				label = "u-boot";
				reg = <0 0x040000>;
			};

			partition@40000 {
				label = "kernel";
				reg = <0x040000 0x500000>;
			};
		};
	};
};
