This document describes the device tree binding for IOMMU test devices.
|
||
|
|
|
||
|
|
The iommu-debug framework can optionally make use of some platform devices
|
||
|
|
for improved standalone testing and other features.
|
||
|
|
|
||
|
|
- compatible: iommu-debug-test
|
||
|
|
|
||
|
|
|
||
|
|
Required properties
|
||
|
|
===================
|
||
|
|
|
||
|
|
- iommus: The IOMMU for the test device (see iommu.txt)
|

|
||
|
|
* need _something_ here to get this node recognized by the
|
||
|
|
* SMMU driver. Our test uses ATOS, which doesn't use SIDs
|
||
|
|
* anyways, so using a dummy value is ok.
