1Sigma Designs Tango4 NAND Flash Controller (NFC)
2
3Required properties:
4
5- compatible: "sigma,smp8758-nand"
6- reg: address/size of nfc_reg, nfc_mem, and pbus_reg
7- dmas: reference to the DMA channel used by the controller
8- dma-names: "rxtx"
9- clocks: reference to the system clock
10- #address-cells: <1>
11- #size-cells: <0>

13Children nodes represent the available NAND chips.
14See Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings.

16Example:
17
18	nandc: nand-controller@2c000 {
19		compatible = "sigma,smp8758-nand";
20		reg = <0x2c000 0x30>, <0x2d000 0x800>, <0x20000 0x1000>;
21		dmas = <&dma0 3>;
22		dma-names = "rxtx";
23		clocks = <&clkgen SYS_CLK>;
24		#address-cells = <1>;
25		#size-cells = <0>;
26
27		nand@0 {
28			reg = <0>; /* CS0 */
29			nand-ecc-strength = <14>;
30			nand-ecc-step-size = <1024>;
31		};
32
33		nand@1 {
34			reg = <1>; /* CS1 */
35			nand-ecc-strength = <14>;
36			nand-ecc-step-size = <1024>;
37		};
