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.

18 The SATA controller-specific device tree bindings are responsible for
19 defining whether each property is required or optional.
