From: Yan Wang <yan.wang at linux.intel.com>

This patch set is only for initial review and trying.
It can work fine on my CNL platform.
I also tested on BYT MB, It doesn't cause regression.

Yan Wang (5):
  APL/CNL: Add stream_tag variable for saving parameter from kernel
    driver.
  APL/CNL: Implement host DMA copy in existed DMA copy API.
  APL/CNL: Save stream tag and host buffer size from kernel driver.
  APL/CNL: Implement host DMA setting and position update on APL/CNL.
  APL/CNL: Initialize DMA trace data structure and definition on
    APL/CNL.
