3This file provides information, what the device node for the
4davinci nand interface contain.
5
6Required properties:
7- compatible: "ti,davinci-nand";
8- reg : contain 2 offset/length values:
9 - offset and length for the access window
10 - offset and length for accessing the aemif control registers
11- ti,davinci-chipselect: Indicates on the davinci_nand driver which
12 chipselect is used for accessing the nand.
13
14Recommended properties :
15- ti,davinci-mask-ale: mask for ale
16- ti,davinci-mask-cle: mask for cle
17- ti,davinci-mask-chipsel: mask for chipselect
18- ti,davinci-ecc-mode: ECC mode valid values for davinci driver:
19 - "none"
20 - "soft"
21 - "hw"
22- ti,davinci-ecc-bits: used ECC bits, currently supported 1 or 4.
23- ti,davinci-nand-buswidth: buswidth 8 or 16
24- ti,davinci-nand-use-bbt: use flash based bad block table support.
