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.
