Ok I see, lets go with 1 intel_ifs device per test-type then.
If I understood things correctly esp. also with the /lib/firmware path then the <N> in intel_ifs_<N> basically specifies the test-type, correct ?
If I have that correct please add this to the ABI documentation in the form of a list with
intel_ifs_<N> <-> test-type
mappings. And also add documentation to each attribute for which test-types the attribute is valid (this can be "all" for e.g. status, to avoid churn when adding more test types).

Yes please.

Hans
