14 * The AIC3X is a driver for a low power stereo audio
15 * codecs aic31, aic32, aic33.
17 * It supports full aic33 codec functionality.
18 * The compatibility with aic32, aic31 is as follows:
20 * ---------------------------------------
21 * MONO_LOUT -> N/A | MONO_LOUT -> N/A
27 * truncated internal functionality in
28 * accordance with documentation
29 * ---------------------------------------
31 * Hence the machine layer should disable unsupported inputs/outputs by
32 * snd_soc_dapm_disable_pin(codec, "MONO_LOUT"), etc.
