* changes:
  Add pcm_get_poll_fd
  Export pcm_mmap_avail

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.

sw_params ioctl() is failing with 'invalid parameter' error
since pointer to pcm_config passed from tinyplay is not zero
initialized, hence invalid values are passed for some
parameters.

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

Tinyalsa doesn't expose an api to call ioctls exposed by
the audio drivers. Add pcm_ioctl() api.

Tinyalsa combines PREPARE and START calls to the driver in the pcm_start()
function.  Typically, this is needed for making a driver allocating hardware
resources that are not related to a PCM stream.

  Revert "Update 64-bit blacklist for tinyalsa"

This reverts commit 6f46701c.

tinyalsa builds fine, and can be used outside mediaserver.

  Update 64-bit blacklist for tinyalsa

tinyalsa is for audio HALs, which are part of mediaserver,
thus should be built 32-bit only

Previously the timebase was not documented.  Now a new pcm_open flag
can be used to specify the clock.  If flag PCM_MONOTONIC is specified,
then pcm_open uses SNDRV_PCM_IOCTL_TTSTAMP with parameter
SNDRV_PCM_TSTAMP_TYPE_MONOTONIC to request timestamps in CLOCK_MONOTONIC.

* commit '673253ac':
  tinyalsa: Add PCM_NORESTART flag.

Add a flag which can be passed to pcm_open (called PCM_NORESTART).
When set on a playback stream, calls to pcm_write will not
automatically attempt to restart an ALSA device in the case of an
underflow.  Instead, it will propagate the first EPIPE error up to the
application to allow it to handle the underflow situation.  Subsequent
calls to pcm_write will attempt to start the pipeline.
