Generally I'd agree here, but as PHY tables include not just setup values, but also platform and chip-specific tunes, I think it's better to have multiple entries rather than having to cope with the possible issues. The only "fallback" compatibles that we have are qcs615-ufs -> sm6115-ufs and qcs8300-ufs -> sa8775p-ufs. Thus I think it's better to stay within the single-compat model.
