What are we supposed to do with things like PCI attached FPGAs and ASICs in that case? They can have host visible devices with physical resources like MMIO ranges and interrupts without those being split up neatly as PCI subfunctions - the original use case for MFD was such ASICs, there's a few PCI drivers in there now. Adding support for those into virtual bus would make it even more of a cut'n'paste of the platform bus than it already is. --TxukmIqg3MmZ0Kmh Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAl76UAwACgkQJNaLcl1U h9DGrwf/dbx5iLf+Ih3TFEH8p4lVh+RAmaAC6LIvz+LoKryJqiE3ZNcSM5/4GPZx C1f4Daud6UOLeFeB7mYI+soHS4RAf5GZ2BOFKBVdJrpDXGALgPQQ7pWTwMioV/BH 9a4gDpBDoEq9BExzZaJmUArvp2o4az9wmP6se2CNV24ofaW1ZAb6HjxYMslnRPeX VaaW93oRtNqFwnU9gOdkeGE7xzz5ZQ2t44bCh9e/3sLw3YExSXEJ+uvsIKbbIiSj AehNFW46JeKU9IwZtx6wSjKDbAaxNb1mSQWqArkLYcYuwpFHvGMwDt2OpteNcCpI 580QPw5rS5wmLtwVZgmI95OAhxaTJQ== =/tbf -----END PGP SIGNATURE----- --TxukmIqg3MmZ0Kmh--
