| 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. |
