title: Common Properties for Parallel AT attachment (PATA) controllers
- Linus Walleij <>
description: |
This document defines device tree properties common to most Parallel
ATA (PATA, also known as IDE) AT attachment storage devices.
It doesn't constitue a device tree binding specification by itself but is
meant to be referenced by device tree bindings.
The PATA (IDE) controller-specific device tree bindings are responsible for
defining whether each property is required or optional.

Specifies the host controller node. PATA host controller nodes are named

DT nodes for ports connected on the PATA host. The master drive will have
ID number 0 and the slave drive will have ID number 1. The PATA port
nodes will be named "ide-port".
