Subject: [alsa-devel] [PATCH 3/5] ASoC: SOF: Intel: hda: add SoundWire stream config/free callbacks
Date: Wed, 23 Oct 2019 16:15:02 -0500 [thread overview]
Message-ID: <20191023211504.32675-4-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20191023211504.32675-1-pierre-louis.bossart@linux.intel.com>
These callbacks are invoked when a matching hw_params/hw_free() DAI
operation takes place, and will result in IPC operations with the SOF
firmware.
