- * 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.
- Example(da850 EVM ):
- nand_cs3@62000000 {
- compatible = "ti,davinci-nand";
- reg = <0x62000000 0x807ff
- 0x68000000 0x8000>;
- ti,davinci-chipselect = <1>;
- ti,davinci-mask-ale = <0>;
- ti,davinci-mask-cle = <0>;
- ti,davinci-mask-chipsel = <0>;
- ti,davinci-ecc-mode = "hw";
- ti,davinci-ecc-bits = <4>;
- ti,davinci-nand-use-bbt;
- partition@180000 {
- label = "ubifs";
- reg = <0x180000 0x7e80000>;
- };
- };
