If an entry in the OF table has no corresponding entr= y in=20 > the I2C table I would consider that as a driver bug. Linus Walleij posted a patch to support DT only probing, but too many side-effects showed up. Some were fixable (probe regressions) and some need more work, if feasible at all. Most prominent is that runtime instantiation of i2c slaves currently needs an entry in the i2c table. --h31gzZEtNLTqOjlF Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJSHN9+AAoJEBQN5MwUoCm2K1cP/3zpfYNXdtAE0fr/YCTZbSzO VZn3LjZXj1zh7FNsySEPkXwVtX2j5ckfJ9/550BNRA5qvOeoCb+ij7/LN7skkoRg 82JxWLmVyZFA8+QVW8uWSKHq/iqNT2nNFoAsocDBOvRoTHnekBQfODqJR8SbrSPd GaBwKJH3WDz0PUhZxpupjeoFM538/VSS9cRgIO6uX1vEj85PpnKYqCNpHHIJQlo/ zJPcDODmIQv8vfaDUS8/nlYwbD93smLkrIl0mzau0nj63zyQkNowIjJ0r/9FqSNc Kd9SbqRWMkrBWFuG2zpWcMfziucBQerlgMqD9hJs0gTm/a6hzl/YRwSJ8atAFmaG 52ApjQ4cHU08TiPXP8ljC5xuT4LPEbX9zPrjFZpFkGf9BNd033RFPZCHnSbqwayI UdBujDuCabPn8CGxuLPJ1eY8CwUt/6/tOAP1j2OeWFH0j0rE/pZTDoQ5m8HVg91E 86+rlfdBXd4+0iF8Uw0oyL4gznAPxqFSiyy+d/K7AMfEBDPaA7y9OW5N30NL7NUO CjhgzyAyzxYNbvGE1MUfdrJjzkuVXi7OqOYYVuneVaBz63a7PWhWn3PCWiqZWX8h rzDHB959I3IFecyj82ylYGcTabjmeKBWbi1XzVsrxEgssNlTKkYz/Q62NbDwMn6C o5hTtR9YHwD9Fk+Uytyv =FPRk -----END PGP SIGNATURE----- --h31gzZEtNLTqOjlF-- -- 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/
