1Hisilicon Hip04 Soc NAND controller DT binding
2
3Required 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
15Optional 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
20The following ECC strength and step size are currently supported:
21
22 - nand-ecc-strength = <16>, nand-ecc-step-size = <1024>
23
24Flash chip may optionally contain additional sub-nodes describing partitions of
25the address space. See partition.txt for more detail.
