+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
+
+Optional properties:
+- arasan,has-mdma: Boolean to support dma transfer for nand read/write.
+
+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>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 14 4>;
+ arasan,has-mdma;
+ partition@0 {
+ label = "filesystem";
+ reg = <0x0 0x0 0x1000000>;
