3 * Apple Onboard Audio driver for tas codec
8 * - How to distinguish between 3004 and versions?
11 * - This codec driver doesn't honour the 'connected'
15 * - Driver assumes that the microphone is always
17 * the input. This should also be a codec-dependent
18 * flag, maybe the codec should have 3 different
23 * - As Apple notes in their code, the tas3004 seems
36 * - this should actually register *two* aoa_codec
49 * codec to refine the transfer_info items in the
54 * a 'clock group id' value so the codec can
