22/* GENERAL NOTES:
23 *
24 * BUGS:
25 * - There are pops (we can't delay in trigger function, cause midlevel
26 *   often need to trigger down and then up very quickly).
27 *   Any ideas?
28 * - Support for 16 bit DMA seems to be broken. I've no hardware to tune it.
29 */
30
31/*
32 * ES1868  NOTES:
33 * - The chip has one half duplex pcm (with very limited full duplex support).
34 *
35 * - Duplex stereophonic sound is impossible.
36 * - Record and playback must share the same frequency rate.
37 *
38 * - The driver use dma2 for playback and dma1 for capture.
39 */
40
41/*
42 * ES1869 NOTES:
43 *
44 * - there are a first full duplex pcm and a second playback only pcm
45 *   (incompatible with first pcm capture)
46 *
47 * - there is support for the capture volume and ESS Spatializer 3D effect.
48 *
49 * - contrarily to some pages in DS_1869.PDF the rates can be set
50 *   independently.
51 *
52 * - Zoom Video is implemented by sharing the FM DAC, thus the user can
53 *   have either FM playback or Video playback but not both simultaneously.
54 *   The Video Playback Switch mixer control toggles this choice.
55 *
56 * BUGS:
57 *
58 * - There is a major trouble I noted:
59 *
60 *   using both channel for playback stereo 16 bit samples at 44100 Hz
61 *   the second pcm (Audio1) DMA slows down irregularly and sound is garbled.
62 *
63 *   The same happens using Audio1 for captureing.
64 *
65 *   The Windows driver does not suffer of this (although it use Audio1
66 *   only for captureing). I'm unable to discover why.
67 *
68 */
69
70/*
71 * ES1879 NOTES:
72 * - When Zoom Video is enabled (reg 0x71 bit 6 toggled on) the PCM playback
73 *   seems to be effected (speaker_test plays a lower frequency). Can't find
74 *   anything in the datasheet to account for this, so a Video Playback Switch
75 *   control has been included to allow ZV to be enabled only when necessary.
76 *   Then again on at least one test system the 0x71 bit 6 enable bit is not
77 *   needed for ZV, so maybe the datasheet is entirely wrong here.
