of this driver.

+* Denali NAND controller
+
+Required properties:
+ - compatible : should be "denali,denali-nand-dt"
+ - reg : should contain registers location and length for data and reg.
+ - reg-names: Should contain the reg names "nand_data" and "denali_reg"
+ - interrupts : The interrupt number.
+ - dm-mask : DMA bit mask
+
+The device tree may optionally contain sub-nodes describing partitions of the
+address space. See partition.txt for more detail.
+
+Examples:
+
+nand: nand@ff900000 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ compatible = "denali,denali-nand-dt";
+ reg = <0xff900000 0x100000>, <0xffb80000 0x10000>;
+ reg-names = "nand_data", "denali_reg";
+ interrupts = <0 144 4>;
+ dma-mask = <0xffffffff>;
+};
