Subject: [PATCH] ASoC: bdw-rt5677: enable runtime channel merge
Date: Wed, 2 Oct 2019 17:04:32 +0800 [thread overview]
Message-ID: <1570007072-23049-1-git-send-email-brent.lu@intel.com> (raw)
In the DAI link "Capture PCM", the FE DAI "Capture Pin" supports 4-channel
capture but the BE DAI supports only 2-channel capture. To fix the channel
mismatch, we need to enable the runtime channel merge for this DAI link.
