2 | * Apple Onboard Audio driver for tas codec | |
3 | * | |
4 | * Copyright 2006 Johannes Berg <johannes@sipsolutions.net> | |
5 | * | |
6 | * GPL v2, can be found in COPYING. | |
7 | * | |
8 | * Open questions: | |
9 | * - How to distinguish between 3004 and versions? | |
10 | * | |
11 | * FIXMEs: | |
12 | * - This codec driver doesn't honour the 'connected' | |
13 | * property of the aoa_codec struct, hence if | |
14 | * it is used in machines where not everything is | |
15 | * connected it will display wrong mixer elements. | |
16 | * - Driver assumes that the microphone is always | |
17 | * monaureal and connected to the right channel of | |
18 | * the input. This should also be a codec-dependent | |
19 | * flag, maybe the codec should have 3 different | |
20 | * bits for the three different possibilities how | |
21 | * it can be hooked up... | |
22 | * But as long as I don't see any hardware hooked | |
23 | * up that way... | |
24 | * - As Apple notes in their code, the tas3004 seems | |
25 | * to delay the right channel by one sample. You can | |
26 | * see this when for example recording stereo in | |
27 | * audacity, or recording the tas output via cable | |
28 | * on another machine (use a sinus generator or so). | |
29 | * I tried programming the BiQuads but couldn't | |
30 | * make the delay work, maybe someone can read the | |
31 | * datasheet and fix it. The relevant Apple comment | |
32 | * is in AppleTAS3004Audio.cpp lines 1637 ff. Note | |
33 | * that their comment describing how they program | |
34 | * the filters sucks... | |
35 | * | |
36 | * Other things: | |
37 | * - this should actually register *two* aoa_codec | |
38 | * structs since it has two inputs. Then it must | |
39 | * use the prepare callback to forbid running the | |
40 | * secondary output on a different clock. | |
41 | * Also, whatever bus knows how to do this must | |
42 | * provide two soundbus_dev devices and the fabric | |
43 | * must be able to link them correctly. | |
44 | * | |
45 | * I don't even know if Apple ever uses the second | |
46 | * port on the tas3004 though, I don't think their | |
47 | * i2s controllers can even do it. OTOH, they all | |
48 | * derive the clocks from common clocks, so it | |
49 | * might just be possible. The framework allows the | |
50 | * codec to refine the transfer_info items in the | |
51 | * usable callback, so we can simply remove the | |
52 | * rates the second instance is not using when it | |
53 | * actually is in use. | |
54 | * Maybe we'll need to make the sound busses have | |
55 | * a 'clock group id' value so the codec can | |
56 | * determine if the two outputs can be driven at | |
57 | * the same time. But that is likely overkill, up | |
58 | * to the fabric to not link them up incorrectly, | |
59 | * and up to the hardware designer to not wire | |
60 | * them up in some weird unusable way. | |
