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