[alsa-devel] user space control app driver interface for sound soc

[Peter Hsiang]

If I want to build an audio user space app to perform things like
transferring large blocks of data to the sound soc codec
using I2C, what is the best kernel driver interface to use 
for this purpose?  Add file interface (read/write/ioctl) in the
sound soc codec driver, or does ALSA already have this?
The soc codec driver needs to co-exist with this mechanism.

Thanks,

Peter
