Subject: [alsa-devel] [PATCH v3 00/11] Add Samus Hotwording for RT5677
Date: Tue,  5 Nov 2019 17:13:25 -0800
Message-ID: <20191106011335.223061-1-cujomalainey@chromium.org> (raw)

This patch series adds the hotwording implementation used in the
Pixelbook on the RT5677 driver.

Known Issues:
There is a known issue where the system will fail to detect a hotword if
suspended while the stream is open. This is due to the fact that the
haswell-dsp suspends its I2S MCLK before the RT5677 suspends which
causes the writes and reads to become corrupted as a result. Any
recommendations to correct this behaviour would be appreciated.

Changes since v1:
* Addressed Mark's and Kuninori's comments
  * Adjusted DAI Links
  * Squashed related patches
  * Removed all kcontrol writes
* Addressed race condition with dapm
* Added firmware boot check
* Moved all clocking to driver API
* Moved DAPM routes that spanned drivers to machine driver

Changes since v2:
* Updated and removed necessary dapm forced power on
* Addressed Cexzary's comments
