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.txt.
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.
