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.

The ID number of the SATA port. Aside with being directly used,
|

each port can have a Port Multiplier attached thus allowing to
|

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