Subject: [PATCH] ASoC: SOF: Intel: add build support for SoundWire
Date: Wed, 24 Jun 2020 01:41:47 +0800	[thread overview]
Message-ID: <20200623174147.22061-1-yung-chuan.liao@linux.intel.com> (raw)

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>

Select SoundWire capabilities on newer Intel platforms, starting with
CannonLake/CoffeeLake/CometLake.

As done for HDaudio, the SoundWire link is an opt-in capability. We
explicitly test for ACPI to avoid warnings on unmet dependencies on
the SoundWire side.
