+Arasan Nand Flash Controller with ONFI 3.1 support
+
+Required properties:
+- compatible: Should be "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 - "clk_sys", "clk_flash"
+	      (See clock bindings for details)
+- clocks: Clock phandles (see clock bindings for details)
+
+Optional properties:
+- arasan,has-mdma: Enables Dma support
+- num-cs: Number of chip selects used
+
+for nand partition information please refer the below file
+Documentation/devicetree/bindings/mtd/partition.txt
+
+Example:
+	nand0: nand@ff100000 {
+		compatible = "arasan,nfc-v3p10"
+		reg = <0x0 0xff100000 0x1000>;
+		clock-name = "clk_sys", "clk_flash"
+		clocks = <&misc_clk &misc_clk>;
+		interrupt-parent = <&gic>;
+		interrupts = <0 14 4>;
+		arasan,has-mdma;
+		num-cs = <1>;
+		partition@0 {
+			label = "filesystem";
+			reg = <0x0 0x0 0x1000000>;
+		};
+		(...)
