+Hisilicon Hip04 Soc NAND controller DT binding
+
+Required properties:
+
+- compatible: Should be "hisilicon,504-nfc".
+- reg: The first contains base physical address and size of
+ NAND controller's registers. The second contains base
+ physical address and size of NAND controller's buffer.
+- interrupts: Interrupt number for nfc.
+- nand-bus-width: See nand.txt.
+- nand-ecc-mode: Support none and hw ecc mode.
+- #address-cells: Partition address, should be set 1.
+- #size-cells: Partition size, should be set 1.
+
+Optional properties:
+
+- nand-ecc-strength: Number of bits to correct per ECC step.
+- nand-ecc-step-size: Number of data bytes covered by a single ECC step.
+
+The following ECC strength and step size are currently supported:
+
+ - nand-ecc-strength = <16>, nand-ecc-step-size = <1024>
+
+Flash chip may optionally contain additional sub-nodes describing partitions of
+the address space. See partition.txt for more detail.
+
+Example:
+
+ nand: nand@4020000 {
+ compatible = "hisilicon,504-nfc";
+ reg = <0x4020000 0x10000>, <0x5000000 0x1000>;
+ interrupts = <0 379 4>;
+ nand-bus-width = <8>;
+ nand-ecc-mode = "hw";
+ nand-ecc-strength = <16>;
+ nand-ecc-step-size = <1024>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ partition@0 {
+ label = "nand_text";
+ reg = <0x00000000 0x00400000>;
+ };
+
+ ...
+
+ };
