| 7 | title: AHCI SATA Controller |
| 8 | |
| 9 | description: | |
| 10 | SATA nodes are defined to describe on-chip Serial ATA controllers. |
| 11 | Each SATA controller should have its own node. |
| 12 | |
| 13 | It is possible, but not required, to represent each port as a sub-node. |
| 14 | It allows to enable each port independently when dealing with multiple |
| 15 | PHYs. |
