Subject: [PATCH 1/4] ASoC: Intel: sof_rt5682: support ALC5682I-VS codec
Date:   Tue, 14 Sep 2021 18:18:44 +0800
Message-Id: <20210914101847.778688-2-brent.lu@intel.com>

Add a new quirk SOF_RT5682S_HEADPHONE_CODEC_PRESENT to support
ALC5682I-VS headphone codec which driver is a new one, rt5682s, with
new macros and functions.
