2 | * ALSA SoC TLV320AIC3X codec driver | |
3 | * | |
4 | * Author: Vladimir Barinov, <vbarinov@ru.mvista.com> | |

12 | * | |
13 | * Notes: | |
14 | * The AIC3X is a driver for a low power stereo audio | |
15 | * codecs aic31, aic32, aic33. | |
16 | * | |
17 | * It supports full aic33 codec functionality. | |
18 | * The compatibility with aic32, aic31 is as follows: | |
19 | * aic32 | aic31 | |
20 | * --------------------------------------- | |
21 | * MONO_LOUT -> N/A | MONO_LOUT -> N/A | |
22 | * | IN1L -> LINE1L | |
23 | * | IN1R -> LINE1R | |
24 | * | IN2L -> LINE2L | |
25 | * | IN2R -> LINE2R | |
26 | * | MIC3L/R -> N/A | |
27 | * truncated internal functionality in | |
28 | * accordance with documentation | |
29 | * --------------------------------------- | |
30 | * | |
31 | * Hence the machine layer should disable unsupported inputs/outputs by | |
a5302181 | 32 | * snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc. |
