  This document defines device tree properties common to most Parallel

14
  ATA (PATA, also known as IDE) AT attachment storage devices.

15
  It doesn't constitute a device tree binding specification by itself but is

16
  meant to be referenced by device tree bindings.

17


18
  The PATA (IDE) controller-specific device tree bindings are responsible for

19
  defining whether each property is required or optional.
