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.
