No, that's a different problem - the context you describe just happens to be your use case but it's in no way universal, there are plenty of expansion boards out there that have devices that use real drivers connected to them normally (and some of those could even be used in the educational contexts you describe). I think the underlying need here is either for a better way of registering things or better tooling around device tree overlays to address the usability issues. --kztsCLGgAaotlup8 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJVPgsIAAoJECTWi3JdVIfQkqkH+gOSCkPFDRokbkbBXoMNxUig 5Ls95JILHjF/Gp+nj+AM5lGtwJUVFn1y5tCFAsbHOMjNmIbeWWBEIvwQnmJSby5e sS5Hh6H6nxD/8jOlSdoJ9vaNKYSWAr131TCWqT8vQjACNk8zROJYv/RrI7NgtFi0 Ap+0JY/bIU/HTEGXNMXYZh8zT5fv9c3rV+TbnR2u87kiyoIGVYMlGKX0DLrbhX6j c8qNgTYO8vtkzSAuh/gCCVHGH31rYBd3vhpD50/pXvmViBXWN2KEocUyn2s1/xUm mP02YDyYPuw1Igm9okVcGLXxkDawJL6rketJvyAVL/sIEiB/A3appK0qnj/AUOo= =0o59 -----END PGP SIGNATURE----- --kztsCLGgAaotlup8-- -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
