1/*
2 * Apple Onboard Audio driver for Onyx codec
3 *
4 * Copyright 2006 Johannes Berg <johannes@sipsolutions.net>
5 *
6 * GPL v2, can be found in COPYING.
7 *
8 *
9 * This is a driver for the pcm3052 codec chip (codenamed Onyx)
10 * that is present in newer Apple hardware (with digital output).
11 *
12 * The Onyx codec has the following connections (listed by the bit
13 * to be used in aoa_codec.connected):
14 * 0: analog output
15 * 1: digital output
16 * 2: line input
17 * 3: microphone input
18 * Note that even though I know of no machine that has for example
19 * the digital output connected but not the analog, I have handled
20 * all the different cases in the code so that this driver may serve
21 * as a good example of what to do.
22 *
23 * NOTE: This driver assumes that there's at most one chip to be
24 * used with one alsa card, in form of creating all kinds
25 * of mixer elements without regard for their existence.
26 * But snd-aoa assumes that there's at most one card, so
27 * this means you can only have one onyx on a system. This
28 * should probably be fixed by changing the assumption of
29 * having just a single card on a system, and making the
30 * 'card' pointer accessible to anyone who needs it instead
31 * of hiding it in the aoa_snd_* functions...
32 *

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.
