title: Common Properties for Parallel AT attachment (PATA) controllers

description: |
This document defines device tree properties common to most Parallel
ATA (PATA, also known as IDE) AT attachment storage devices.
It doesn't constitute 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.
properties:
$nodename:
pattern: "^ide(@.*)?$"
description:
Specifies the host controller node. PATA host controller nodes are named
"ide".
"#address-cells":
const: 1
"#size-cells":
const: 0
patternProperties:
"^ide-port@[0-1]$":
description: |
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".
