+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";
+               };
+       };
