Sigma Designs Tango4 NAND Flash Controller (NFC)

Required properties:

- compatible: "sigma,smp8758-nand"
- reg: address/size of nfc_reg, nfc_mem, and pbus_reg
- dmas: reference to the DMA channel used by the controller
- dma-names: "rxtx"
- clocks: reference to the system clock
- #address-cells: <1>
- #size-cells: <0>

Children nodes represent the available NAND chips.
See Documentation/devicetree/bindings/mtd/nand.txt for generic bindings.

Example:

	nandc: nand-controller@2c000 {
		compatible = "sigma,smp8758-nand";
		reg = <0x2c000 0x30>, <0x2d000 0x800>, <0x20000 0x1000>;
		dmas = <&dma0 3>;
		dma-names = "rxtx";
		clocks = <&clkgen SYS_CLK>;
		#address-cells = <1>;
		#size-cells = <0>;

		nand@0 {
			reg = <0>; /* CS0 */
			nand-ecc-strength = <14>;
			nand-ecc-step-size = <1024>;
		};

		nand@1 {
			reg = <1>; /* CS1 */
			nand-ecc-strength = <14>;
			nand-ecc-step-size = <1024>;
		};
	};
