1 | NAND support for Marvell Orion SoC platforms |
| 2 | ||
| 3 | Required properties: | |
| 77843504 | 4 | - compatible : "marvell,orion-nand". |
| a0fabf72 JL |
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 | |
| 16 | address space. See partition.txt for more detail. | |
| 17 | ||
| 18 | Example: | |

| 20 | nand@f4000000 { | |
| 21 | #address-cells = <1>; | |
| 22 | #size-cells = <1>; | |
| 23 | cle = <0>; | |
| 24 | ale = <1>; | |
| 25 | bank-width = <1>; | |
| 26 | chip-delay = <25>; | |
