| 13 | This document defines device tree properties common to most Serial | |
| 14 | AT attachment (SATA) storage devices. It doesn't constitute a device tree | |
| 15 | binding specification by itself but is meant to be referenced by device | |
| 16 | tree bindings. | |
| 17 | ||
| 18 | The SATA controller-specific device tree bindings are responsible for | |
| 19 | defining whether each property is required or optional. | |

| 46 | The ID number of the drive port SATA can potentially use a port | |
| 47 | multiplier making it possible to connect up to 15 disks to a single | |
| 48 | SATA port. | |
