This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

|
|
* Notes:
|
|
* The AIC3X is a driver for a low power stereo audio
|
|
* codecs aic31, aic32, aic33.
|
|
*
|
|
* It supports full aic33 codec functionality.
|
|
* The compatibility with aic32, aic31 is as follows:
|
|
* aic32 | aic31
|
|
* ---------------------------------------
|
|
* MONO_LOUT -> N/A | MONO_LOUT -> N/A
|
|
* | IN1L -> LINE1L
|
|
* | IN1R -> LINE1R
|
|
* | IN2L -> LINE2L
|
|
* | IN2R -> LINE2R
|
|
* | MIC3L/R -> N/A
|
|
* truncated internal functionality in
|
|
* accordance with documentation
|
|
* ---------------------------------------
|
|
*
|
|
* Hence the machine layer should disable unsupported inputs/outputs by
|
|
* snd_soc_dapm_set_endpoint(codec, "MONO_LOUT", 0), etc.
