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-controller.yaml.
- 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 mtd.yaml 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>;
};
...
};
