   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.

   21 properties:
   22   $nodename:
   23     pattern: "^sata(@.*)?$"

   26       "sata"

   38       nodes will be named "sata-port".

   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.
