[alsa-devel] Timer interface

I am extending my ALSA driver in order to support software mixing. Driver
currently supports both MMAP and RW access modes. However, I am still not
able to use dmix since it requires timer interface to be implemented.
My hardware does not generate interrupts at the period boundary but issues
timer interrupts at a fixed timer rate. 
Could you please point me to the document or sample driver that can help me
to fully understand timer interface concept (especially for High frequency
timer interrupts)?
