Subject: [alsa-devel] [PATCH v7 1/2] dt-bindings: ASoC: Add WSA881x bindings
Date: Wed, 9 Oct 2019 09:51:07 +0100 [thread overview]
Message-ID: <20191009085108.4950-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20191009085108.4950-1-srinivas.kandagatla@linaro.org>
This patch adds bindings for WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier also has a simple thermal sensor for
over temperature and speaker protection.
