The "do what you want" ALSA's hwdep device / interface can be used to transfer 
data in/out from SRC using custom read/write/ioctl/mmap syscalls. The question 
is, if the changes cannot be more simpler for the first implementation keeping 
the hardware enumeration in one subsystem where is the driver code placed. I 
also see the benefit to reuse the already existing framework (but is v4l2 the 
right one?).
