13  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 constitue 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.
