No, that's really not going to work very well - having the same CODEC with very tightly coupled clocking connected into three cards is just going to be a mess, especially for the WM8958 where AIF3 is mostly just a pinmux to the other two DAIs rather than something that could ever be fully independent. --/IjyWiMc6vC4PmW7 Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJW1kMuAAoJECTWi3JdVIfQL5EH/R6PdruV8icgZkHUYFwrJJrG 7hbKeUhUlczgaFvHn2xtdOL9ifkrQ/TxYySdQ/aHNLQl1HRT32O9qAywwTPO1fAS UV+hAp/XHl48LGyH9k7mvVrYi9iguqteFLMJY8mz1aTmy6Mvg5OgyxKXdn0Ps94t EFQ9+pR/D74UVY4XYK3S/dgo/85HtMW4aNqwHYQLgiTZdFwCQQn6WzMnEWzKm1wK P9LIBNyyDRil8pV3QefAPYeWMv/5lFQLytFWLimphSIxeRmjVcVkQA5bvJdPUhdm M7p8Yz/8U/2VuGW5UO2sKNTHdUo3bgdbXRDh1QbbUIg/2KaDn4aPG/U7F4CbvzE= =Qpb5 -----END PGP SIGNATURE----- --/IjyWiMc6vC4PmW7-- --===============4792338509910071112== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline --===============4792338509910071112==--
