[PATCH v6 6/7] iommu/arm-smmu-qcom: Use the custom fault handler on more platforms

From: Georgi Djakov
Date: Thu Mar 07 2024 - 14:09:23 EST


The TBU support is now available, so let's allow it to be used on other
platforms that have the Qualcomm SMMU-500 implementation with TBUs. This
will allow the context fault handler to query the TBUs when a context
fault occurs.
