Subject: [alsa-devel] [PATCH v11 1/2] dt-bindings: ASoC: Add WSA881x bindings
Date: Tue, 7 Jan 2020 13:59:28 +0000 [thread overview]
Message-ID: <20200107135929.3267-2-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20200107135929.3267-1-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.
