  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.

          each port can have a Port Multiplier attached thus allowing to

          access more than one drive by means of a single SATA port.
