0001 Hisilicon Hip04 Soc NAND controller DT binding
0002
0003 Required properties:
0004
0005 - compatible: Should be "hisilicon,504-nfc".
0006 - reg: The first contains base physical address and size of
0007 NAND controller's registers. The second contains base
0008 physical address and size of NAND controller's buffer.
0009 - interrupts: Interrupt number for nfc.
0010 - nand-bus-width: See nand-controller.yaml.
0011 - nand-ecc-mode: Support none and hw ecc mode.
0012 - #address-cells: Partition address, should be set 1.
0013 - #size-cells: Partition size, should be set 1.
0014
0015 Optional properties:
0016
0017 - nand-ecc-strength: Number of bits to correct per ECC step.
0018 - nand-ecc-step-size: Number of data bytes covered by a single ECC step.
0019
0020 The following ECC strength and step size are currently supported:
0021
0022 - nand-ecc-strength = <16>, nand-ecc-step-size = <1024>
0023
0024 Flash chip may optionally contain additional sub-nodes describing partitions of
0025 the address space. See partition.txt for more detail.
0026
0027 Example:
0028
0029 nand: nand@4020000 {
0030 compatible = "hisilicon,504-nfc";
0031 reg = <0x4020000 0x10000>, <0x5000000 0x1000>;
0032 interrupts = <0 379 4>;
0033 nand-bus-width = <8>;
0034 nand-ecc-mode = "hw";
0035 nand-ecc-strength = <16>;
0036 nand-ecc-step-size = <1024>;
0037 #address-cells = <1>;
0038 #size-cells = <1>;
0039
0040 partition@0 {
0041 label = "nand_text";
0042 reg = <0x00000000 0x00400000>;
0043 };
0044
0045 ...
0046
0047 };
