[ALSA] ASoC TLV320AIC3X codec driver
This patch adds ALSA SoC support for TI TLV320AIC3X audio codecs. The features that are supported: o Capture/Playback/Bypass. o 16/20/24/32 bit audio. o 8k - 96k sample rates. o codec master only mode o DAPM.

2 * ALSA SoC TLV320AIC3X codec driver

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
32 * snd_soc_dapm_set_endpoint(codec, "MONO_LOUT", 0), etc.
