[PATCH v3 12/21] remoteproc: Use iommu_paging_domain_alloc()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



An iommu domain is allocated in rproc_enable_iommu() and is attached to
rproc->dev.parent in the same function.

Use iommu_paging_domain_alloc() to make it explicit.
