   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.
   20 
   21 properties:
   22   $nodename:
   23     pattern: "^ide(@.*)?$"
   24     description:
   25       Specifies the host controller node. PATA host controller nodes are named
   26       "ide".

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