+Hisilicon Hip04 Soc NAND controller DT binding
+
+Required properties:
+- compatible: Should be "hisilicon,nfc504".
+- reg: Contain registers location and length for reg and data.
+- interrupts: Interrupt number for nfc.
+- nand-bus-width: See nand.txt.
+- nand-ecc-mode: See nand.txt.
+- hisi,nand-ecc-bits: ECC bits type support.
+ <0>: none ecc
+ <1>: Can correct 1bit per 512byte.
+ <6>: Can correct 16bits per 1K byte.
+- #address-cells: partition address.
+- #size-cells: partition size.
+
+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,nfc504";
+ reg = <0x4020000 0x10000>, <0x5000000 0x1000>;
+ interrupts = <0 379 4>;
+ nand-bus-width = <8>;
+ nand-ecc-mode = "hw";
+ hisi,nand-ecc-bits = <1>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ partition@0 {
+ label = "nand_text";
+ reg = <0x00000000 0x00400000>;
+ };
+
+ ...
+
+ };
