 *		  caller to test reuse of existing domains. Otherwise, it may
 *		  still represent some other fundamental problem
 * * ENOMEM	- out of memory
 * * ENOSPC	- non-ENOMEM type of resource allocation failures
 * * EBUSY	- device is attached to a domain and cannot be changed
 * * ENODEV	- device specific errors, not able to be attached
 * * <others>	- treated as ENODEV by the caller. Use is discouraged
 * @set_dev_pasid: set or replace an iommu domain to a pasid of device. The pasid of
 *                 the device should be left in the old config in error case.
 * @map_pages: map a physically contiguous set of pages of the same size to
