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.

ID number 0 and the slave drive will have ID number 1. The PATA port
|

nodes will be named "ide-port".
