Subject: [alsa-devel] [PATCH v8 1/3] dt-bindings: ASoC: Add WSA881x bindings
Date: Fri, 11 Oct 2019 16:24:44 +0100
Message-ID: <20191011152446.5925-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20191011152446.5925-1-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.

+  WSA8810 is a class-D smart speaker amplifier and WSA8815
+  is a high-output power class-D smart speaker amplifier.
+  Their primary operating mode uses a SoundWire digital audio
+  interface. This binding is for SoundWire interface.
