| 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) |

| Example |

| iommu_test_device { |
| compatible = "iommu-debug-test"; |
| /* |
| * 42 shouldn't be used by anyone on the cpp_fd_smmu. We just |
| * 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. |
