[PATCH v3 04/12] iommu: Add iris-vpu-bus to iommu_buses
From: Vishnu Reddy
Date: Mon Apr 27 2026 - 23:57:45 EST
From: Vikash Garodia <vikash.garodia@xxxxxxxxxxxxxxxx>
Add iris-vpu-bus to iommu_buses[] to register the bus notifier callbacks
for device add and removal events. This ensures that when a device is
registered on iris-vpu-bus, the notifier triggers dma_configure(),
which sets up the IOMMU context for that device.
