    1 Hisilicon Hip04 Soc NAND controller DT binding
    2 
    3 Required properties:
    4 
    5 - compatible:          Should be "hisilicon,504-nfc".
    6 - reg:                 The first contains base physical address and size of
    7                        NAND controller's registers. The second contains base
    8                        physical address and size of NAND controller's buffer.
    9 - interrupts:          Interrupt number for nfc.
   10 - nand-bus-width:      See nand-controller.yaml.
   11 - nand-ecc-mode:       Support none and hw ecc mode.
   12 - #address-cells:      Partition address, should be set 1.
   13 - #size-cells:         Partition size, should be set 1.
   14 
   15 Optional properties:
   16 
   17 - nand-ecc-strength:   Number of bits to correct per ECC step.
   18 - nand-ecc-step-size:  Number of data bytes covered by a single ECC step.
   19 
   20 The following ECC strength and step size are currently supported:
   21 
   22  - nand-ecc-strength = <16>, nand-ecc-step-size = <1024>
   23 
   24 Flash chip may optionally contain additional sub-nodes describing partitions of
   25 the address space. See partition.txt for more detail.
   26 
   27 Example:
   28 
   29         nand: nand@4020000 {
   30                 compatible = "hisilicon,504-nfc";
   31                 reg = <0x4020000 0x10000>, <0x5000000 0x1000>;
   32                 interrupts = <0 379 4>;
   33                 nand-bus-width = <8>;
   34                 nand-ecc-mode = "hw";
   35                 nand-ecc-strength = <16>;
   36                 nand-ecc-step-size = <1024>;
   37                 #address-cells = <1>;
   38                 #size-cells = <1>;
   39 
   40                 partition@0 {
   41                         label = "nand_text";
   42                         reg = <0x00000000 0x00400000>;
   43                 };
   44 
   45                 ...
   46 
   47         };
