From: Joerg Roedel<jroedel@xxxxxxx> Add call-backs to 'struct iommu_ops' as an alternative to the add_device() and remove_device() call-backs, which will be removed when all drivers are converted. The new call-backs will not setupt IOMMU groups and domains anymore, so also add a probe_finalize() call-back where the IOMMU driver can do per-device setup work which require the device to be set up with a group and a domain.
The subject is inaccurate. probe_device() and release_device() are added to replace the add and remove pair. Best regards, baolu
