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: "nfc_sbox"

- 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 = "nfc_sbox";

		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>;

		};

	};
