+* Oxford Semiconductor OXNAS NAND Controller
+
+Please refer to nand.txt for generic information regarding MTD NAND bindings.
+
+Required properties:
+ - compatible: "oxsemi,ox820-nand"
+ - reg: Base address and length for NAND mapped memory.
+
+Optional Properties:
+ - clocks: phandle to the NAND gate clock if needed.
+ - resets: phandle to the NAND reset control if needed.
+
+Example:
+
+nandc: nand-controller@41000000 {
+ compatible = "oxsemi,ox820-nand";
+ reg = <0x41000000 0x100000>;
+ clocks = <&stdclk CLK_820_NAND>;
+ resets = <&reset RESET_NAND>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ nand@0 {
+ reg = <0>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ nand-ecc-mode = "soft";
+ nand-ecc-algo = "hamming";
+
+ partition@0 {
+ label = "boot";
+ reg = <0x00000000 0x00e00000>;
+ read-only;
+ };
+
+ partition@e00000 {
