hello,

I am providing control interface for my driver to access from user space
with functions get & put .
 ( driver is for arm platform ) .

I want to know

 * while creating new controls should I be allowed to create my hardware
specific controls like gain, power, rate & other codec specific parameters.
        or  should I take care of mapping OSS mixer controls to ALSA mixer.
 * How user comes to know what controls are available & the valid range of
values for sliders & switches.
As I'm new to ALSA, can anyone explain me in detail, in this ragard.
Thanks & Regards
Pavana S
