| * 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. |
| |
| nand device bindings may contain additional sub-nodes describing |
| partitions of the address space. See partition.txt for more detail. |
