| Atmel NAND flash |
| |
| Required properties: |
| - compatible : "atmel,at91rm9200-nand". |
| - reg : should specify localbus address and size used for the chip, |
| and if availlable the ECC. |
| - atmel,nand-addr-offset : offset for the address latch. |
| - atmel,nand-cmd-offset : offset for the command latch. |
| - #address-cells, #size-cells : Must be present if the device has sub-nodes |
| representing partitions. |
| |
| - gpios : specifies the gpio pins to control the NAND device. detect is an |
| optional gpio and may be set to 0 if not present. |
| |
| Optional properties: |
| - nand-ecc-mode : String, operation mode of the NAND ecc mode, soft by default. |
| Supported values are: "none", "soft", "hw", "hw_syndrome", "hw_oob_first", |
| "soft_bch". |
| - nand-bus-width : 8 or 16 bus width if not present 8 |
| - nand-on-flash-bbt: boolean to enable on flash bbt option if not present false |
| |

| nand0: nand@40000000,0 { |
