Subject: [PATCH 0/2] ASoC: SOF: compress: Add support for timestamp on capture

The purpose of this patch series is to add support for
timestamping on capture direction using the compress
API.

This is simply done by splitting sof_compr_copy into 2
functions: sof_compr_copy_playback and sof_compr_copy_capture.
Each of these functions handles one of the possible directions:
capture or playback and is called in sof_compr_copy based on
the stream's direction.

The only difference between sof_compr_copy_playback and
sof_compr_copy_capture is the fact that on playback case
we need to copy data from user space and on capture we
need to copy data to user space.

Laurentiu Mihalcea (2):
  ASoC: SOF: compress: Move sof_compr_copy functionality
  ASoC: SOF: compress: Add copy function for capture case
