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>;
|
|
};
|
|
|
|
...
|
|
|
|
};
