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. */ iommus = <&cpp_fd_smmu 42>; };
