+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:
+
+ nand: nand@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>;
+ };
+ };
