Subject: [PATCH 04/10] ASoC: Intel: boards: sof_sdw: add SoundWire mockup codecs for tests
Date:   Wed, 14 Jul 2021 11:22:03 +0800
Message-Id: <20210714032209.11284-5-yung-chuan.liao@linux.intel.com>
In-Reply-To: <20210714032209.11284-1-yung-chuan.liao@linux.intel.com>

Precedence: bulk

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

Add support for SoundWire mockup devices. The configurations assume the
same topology as the CML SoundWire devices and can be used to test the
SOF firmware on a development board (RVP, UpExtreme) without any
hardware connected.
