      tinyalsa: pcm: open pcm driver in non blocking mode · 51f47ff3
      vivek mehta authored 
      - in current implementation pcm open call is blocking hence if pcm_open
  is done on same driver twice second pcm open will get blocked till
  first instance of the PCM driver is not released.
  In times this will result in deadlock.

- fix this issue by making PCM open in non-blocking mode.

- after pcm open is successful, in non-blocking mode, change the device
  mode to blocking again to make sure rest of the operation on the
  driver, like read / write calls, are always called in blocking mode.

Also fix jump to wrong label in case of failure before mmap().

      Add pcm_get_poll_fd · cefba1e3
      Dylan Reid authored 
      
Similar to ALSA snd_pcm_get_poll_fd, this will allow a user to wait for
a sound device to have data in a poll(2) call.  The hotword thread will
use this to wait for a message on its socket or for audio data to become
ready.

This is useful for timer based wakeups and for checking how much data
has been captured by a hotwording device.

      Tinyalsa always set silence_size to zero. Add support to set this
pcm software parameter as required.
