| 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 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. |

| 21 | properties: |

| 25 | Specifies the host controller node. PATA host controller nodes are named |
| 26 | "ide". |

| 36 | description: | |
| 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". |
