[alsa-devel] New Audio Driver Design

  I am to write an ALSA driver for my SOC which has a dedicated DSP
subsystem which can
be loaded with decoder instructions and parameteres, and then we load it
with encoded data. The dsp then decodes the data and sends it to the PCM

Could someone please refer me to some similar driver/codec which already
does that?
If not, how should i design the driver?
    :- Should I load the encoder inst/params using firmware API? Then, which
API should I use to submit encoded data to the DSP?

Any pointers please?
