I've got practical systems where there are multiple buses physically connected, though in practice almost always only one is actually used at runtime when it's I2C and SPI there are some systems (usually with other buses) where you might want to use more than one bus. Not sure those buses will fit in here though. --T7mxYSe680VjQnyC Content-Type: application/pgp-signature; name="signature.asc" Content-Description: Digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.12 (GNU/Linux) iQIcBAEBAgAGBQJQl5tgAAoJELSic+t+oim91GMP/iyqvgjKkbCGjnaffRPy1vXD s/up+6mOdqNNcz559ti7LE0JcK2nXab0ffcFT0cbhQ46pTdrPqZS7FdEvHqeOPWK WDpQCPqVfWTBpQC8CttjRhUdtBFnDrfbJeHcvsz4OboW7EMkXxRilfES0yYuUOSV OQJ4dJvjtfBawsN19gs607rOPMCBjKtsHdhRtqV4pL4x3dzp8WwDSbgxSJQ1doxm REgOtrAgCOdUisacRpm1epu6rLPfYsiDrN9Pho47gjUbSNL2Jo+6FJupcFxYjjGL Zt6BhGArrPkCHH0Ziyb0epyQIIWBo88SQSTYZiPRF1CXbiVtH0ZRoODwyCa0FdeC zd8LIRobvsDWgNdCD1dtwFr27YyeLOtHcK2rCGC7ttbtaWhmrfJkKlLc7fBqCm+v XF1vyzSAdAMk4AsYvm33DGhXubhDPIPyMbTBicx5eNMn0StEqVeauK1HZGuAa8rM xsVSKBOf/cA5zxRQQD8ZdgFjtYUpWeqpP10H3MOzapBl9G/QAnVryLH+2A65bH3y yk7S2sgDeDwTrkMQKmpDVd5WHVfxTRi1txEvrcbI0QVRk8MoWA2g8DvWMKReGvf4 evqZ1NrUKDqWNVopXQH6iQcFVgdXWyHtRsWyo0b+GpepSVl4DJDpPhGFB0k4aD+6 6KFEpuVpJqiRA3x2CiKp =hlgk -----END PGP SIGNATURE----- --T7mxYSe680VjQnyC-- -- 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/
