Subject: [RFC PATCH 11/12] ASoC: SOF: Intel: hda: add SoundWire stream config/free callbacks
Date: Mon, 16 Sep 2019 16:42:50 -0500 [thread overview]
Message-ID: <20190916214251.13130-12-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20190916214251.13130-1-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.
