from what this patch does the tsm core supports device types other
than PCI (though currently only PCI is supported).

suppose there may be other bus-specific scope values accepted?

if yes here better say that for the meaning of scope values please
refer to bus specific tsm definitions. Then in the following detailed
description take PCI as an example referring to pci_tsm_req_scope.
