^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 7) * Open questions:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 8) * - How to distinguish between 3004 and versions?
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 9) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) * FIXMEs:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) * - This codec driver doesn't honour the 'connected'
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) * property of the aoa_codec struct, hence if
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) * it is used in machines where not everything is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 14) * connected it will display wrong mixer elements.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) * - Driver assumes that the microphone is always
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) * monaureal and connected to the right channel of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17) * the input. This should also be a codec-dependent
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) * flag, maybe the codec should have 3 different
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) * bits for the three different possibilities how
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) * it can be hooked up...
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) * But as long as I don't see any hardware hooked
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) * up that way...
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) * - As Apple notes in their code, the tas3004 seems
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) * to delay the right channel by one sample. You can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) * see this when for example recording stereo in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26) * audacity, or recording the tas output via cable
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) * on another machine (use a sinus generator or so).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) * I tried programming the BiQuads but couldn't
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) * make the delay work, maybe someone can read the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) * datasheet and fix it. The relevant Apple comment
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) * is in AppleTAS3004Audio.cpp lines 1637 ff. Note
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 32) * that their comment describing how they program
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 33) * the filters sucks...
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 34) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 35) * Other things:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 36) * - this should actually register *two* aoa_codec
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) * structs since it has two inputs. Then it must
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) * use the prepare callback to forbid running the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) * secondary output on a different clock.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) * Also, whatever bus knows how to do this must
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) * provide two soundbus_dev devices and the fabric
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) * must be able to link them correctly.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 43) *
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 44) * I don't even know if Apple ever uses the second
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 45) * port on the tas3004 though, I don't think their
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 46) * i2s controllers can even do it. OTOH, they all
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 47) * derive the clocks from common clocks, so it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 48) * might just be possible. The framework allows the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 49) * codec to refine the transfer_info items in the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 50) * usable callback, so we can simply remove the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 51) * rates the second instance is not using when it
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 52) * actually is in use.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 53) * Maybe we'll need to make the sound busses have
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 54) * a 'clock group id' value so the codec can
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 55) * determine if the two outputs can be driven at
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 56) * the same time. But that is likely overkill, up
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 57) * to the fabric to not link them up incorrectly,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 58) * and up to the hardware designer to not wire
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 59) * them up in some weird unusable way.
