+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
+- interrupt-parent:	Interrupt controller the interrupt is routed through
+- 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";
+		};
+	};
