title: Common Properties for Serial AT attachment (SATA) controllers
maintainers:
- Linus Walleij <linus.walleij@linaro.org>
description: |
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.

pattern: "^sata(@.*)?$"

Specifies the host controller node. SATA host controller nodes are named
"sata"

nodes will be named "sata-port".

description:
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.
