+Arasan NAND Flash Controller with ONFI 3.1 support
+
+Required properties:
+- compatible: Should be "xlnx,zynqmp-nand", "arasan,nfc-v3p10"
+- reg: Memory map for module access
+- interrupts: Should contain the interrupt for the device
+- clock-name: List of input clocks - "sys", "flash"
+ (See clock bindings for details)
+- clocks: Clock phandles (see clock bindings for details)
+
+Required properties for child node:
+- nand-ecc-mode: see nand.txt
+
+For NAND partition information please refer the below file
+Documentation/devicetree/bindings/mtd/partition.txt
+
+Example:
+ nfc: nand@ff100000 {
+ compatible = "xlnx,zynqmp-nand", "arasan,nfc-v3p10";
+ reg = <0x0 0xff100000 0x1000>;
+ clock-name = "sys", "flash";
+ clocks = <&misc_clk &misc_clk>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 14 4>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ nand@0 {
+ reg = <0>;
+ nand-ecc-mode = "hw";
+ };
+ };
