| 2 | |
| 3 | Required properties: |
| 4 | - compatible : The possible values are: |
| 5 | "samsung,s3c2410-nand" |
| 6 | "samsung,s3c2412-nand" |
| 7 | "samsung,s3c2440-nand" |
| 8 | - reg : register's location and length. |
| 9 | - #address-cells, #size-cells : see nand-controller.yaml |
| 10 | - clocks : phandle to the nand controller clock |
| 11 | - clock-names : must contain "nand" |
| 12 | |
| 13 | Optional child nodes: |
| 14 | Child nodes representing the available nand chips. |
| 15 | |
| 16 | Optional child properties: |
| 17 | - nand-ecc-mode : see nand-controller.yaml |
| 18 | - nand-on-flash-bbt : see nand-controller.yaml |
| 19 | |
| 20 | Each child device node may optionally contain a 'partitions' sub-node, |
| 21 | which further contains sub-nodes describing the flash partition mapping. |
