domain_alloc_user op already accepts user flags for domain allocation, add a parent domain pointer and a driver specific user data support as well. The user data would be tagged with a type for iommu drivers to add their own driver specific user data per hw_pagetable. Add a struct iommu_user_data as a bundle of data_ptr/data_len/type from an iommufd core uAPI structure. Make the user data opaque to the core, since a userspace driver must match the kernel driver. In the future, if drivers share some common parameter, there would be a generic parameter as well.
