| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "marvell,orion-nand". |
| 5 | - reg : Base physical address of the NAND and length of memory mapped |
| 6 | region |
| 7 | |
| 8 | Optional properties: |
| 9 | - cle : Address line number connected to CLE. Default is 0 |
| 10 | - ale : Address line number connected to ALE. Default is 1 |
| 11 | - bank-width : Width in bytes of the device. Default is 1 |
| 12 | - chip-delay : Chip dependent delay for transferring data from array to read |
| 13 | registers in usecs |
| 14 | |
| 15 | The device tree may optionally contain sub-nodes describing partitions of the |
