Subject: [PATCH v4 3/4] dt-bindings: ASoC: Add WSA881x bindings
Date: Thu, 22 Aug 2019 23:36:05 +0100 [thread overview]
Message-ID: <20190822223606.6775-4-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20190822223606.6775-1-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.
