* Texas Instruments Davinci NAND
|
||
|
|
||
|
This file provides information, what the device node for the
|
||
|
davinci nand interface contain.
|
||
|
|
||
|
Required properties:
|
||
|
- compatible: "ti,davinci-nand";
|
||
|
- reg : contain 2 offset/length values:
|
||
|
- offset and length for the access window
|
||
|
- offset and length for accessing the aemif control registers
|
||
|
- ti,davinci-chipselect: Indicates on the davinci_nand driver which
|
||
|
chipselect is used for accessing the nand.
|
||
|
|
||
|
Recommended properties :
|
||
|
- ti,davinci-mask-ale: mask for ale
|
||
|
- ti,davinci-mask-cle: mask for cle
|
||
|
- ti,davinci-mask-chipsel: mask for chipselect
|
||
|
- ti,davinci-ecc-mode: ECC mode valid values for davinci driver:
|
||
|
- "none"
|
||
|
- "soft"
|
||
|
- "hw"
|
||
|
- ti,davinci-ecc-bits: used ECC bits, currently supported 1 or 4.
|
||
|
- ti,davinci-nand-buswidth: buswidth 8 or 16
|
||
|
- ti,davinci-nand-use-bbt: use flash based bad block table support.
|
||
|
|
||
|
Example (enbw_cmc board):
|
||
|
aemif@60000000 {
|
