I would love to see us drop this silly upstream/downstream compatible string naming scheme and just use 2711 (or 7211 for modules shared with 7211 that were enabled there first). However, I don't feel that strongly about it when I'm not the one doing the work. Other than the SPI shared interrupt change that looks dodgy, and a preference for the clock change being data-driven instead, I would be willing to ack the whole thing. --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEE/JuuFDWp9/ZkuCBXtdYpNtH8nugFAl0wvi4ACgkQtdYpNtH8 nuiZRBAAljJpthQvWXCClvxeRHJYGp0vPGv1je6Rn2HvKTfNezTxpRWlVbfr0hj6 jOOCNheqif3GOEz0ExfQM4Fwvdv1W/bt4594sEm9RoXGjxuQioMYsf5rSs0fYN+l hMEGfJ0lOLU1qeeeyFMJRu4O+LM7ZY8UPa2BQo3btYBHfuG/W1lgTTLl1YWe90fQ dBXJTxoKfdpa0kOhsw1LbkMsgbm32+zG97tMdzNAOVP4NeDfnmrr+LVWTq09N8af 0PSkmf3GHmwXAkZ21y2g0MsviJgFBZIOPWv4YVZUknz4uyflxjnInVTp4Q8i7VC8 iS20wEgmzcuIOZq7iyTCIUQXHbite6kzAbNT11VxBiesRg+YW4CWcMvFasZ6AzcD plLuHXgIzKBOfN+xeQB36Zo9cEcHHe+2uH8uZNvgLVcWLJuzs0EWCFdJLQSCDkX9 pVaIEXtRl7Cbux7sdVmWFyFuHwgHjZ4fnmykDBSNubS/+OjjvSL05Pn+hzelxJam XzMY/v38TY5xRCZQlWrc7Lyhij686M9rrCU9h/n4AxQb9uZ6REE3JLh3dHzWbSD9 FXEAAQU24Rzix4iBHu/6NyXU/xFp9WuZ2uMqeNLQuDQXbxqp6KOq71Ti//aTtQwN wDDt0T904SpZrjJRCUSjMqRECziHcCp6lnNg+V+Dj+fGKO8rOdc= =Zs2Q -----END PGP SIGNATURE----- --=-=-=-- --===============0045168248185277525== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel --===============0045168248185277525==--
