[alsa-devel] Dynamic control commands that match the downloadable DSP firmware

Hi Mark and Everyone,

For codecs with a programmable DSP core, one needs to provide the amixer controls for the 'soft' features.  As there could be multiple DSP firmware images for different applications, it would be nice if a single codec driver source can support an unlimited combination of commands for DSP firmware features.  

Rather than hard coding the control commands in the driver directly, wouldn't it be cool if, in addition to the firmware being loaded from file, the control commands information can be loaded from file as well.  Then the driver would dynamically create and install the control commands the same way we already do for the EQ.

What do you think?
