| 9 | - interrupts: The interrupt to map |
| 10 | - #address-cells: Set to <1> if the node includes partitions |
| 11 | |

| 16 | - marvell,nand-keep-config: Set to keep the NAND controller config as set |
| 17 | by the bootloader |
| Brian Norris | 0542e13 | 2015-02-28 01:25:17 -0800 | [diff] [blame] | 18 | - num-cs: Number of chipselect lines to use |

| Ezequiel Garcia | fe4fd75 | 2014-05-14 14:58:09 -0300 | [diff] [blame] | 21 | - nand-ecc-strength: number of bits to correct per ECC step |
| 22 | - nand-ecc-step-size: number of data bytes covered by a single ECC step |
| 23 | |
| 24 | The following ECC strength and step size are currently supported: |
| 25 | |
| 26 | - nand-ecc-strength = <1>, nand-ecc-step-size = <512> |
| 27 | - nand-ecc-strength = <4>, nand-ecc-step-size = <512> |
| 28 | - nand-ecc-strength = <8>, nand-ecc-step-size = <512> |
