help
Support for sound devices specific to ARM architectures.
Drivers that are implemented on ASoC can be found in
"ALSA for SoC audio support" section.

To compile this driver as a module, choose M here: the module
will be called snd-mc13783.

Say Y here to include support mixing for soundcards based on the
MC13783 chip. This supports audio stream mixing on VCODEC for mc13783 based platforms.
Analog mixng as well as Digital mixing can be tested on these platforms.
As of now , mixing of mono files only are supported in Digital Mixing since it is done on VCODEC.
SSI 2 channel mode is used to mix 2 streams on a single SSI. This is supported on all platforms except imx27ads(imx27ads - Analog mixing only).

It will use IRAM as the DMA buffer of ALSA playback.
