Subject: [PATCH v4 08/10] dt-bindings: sound: Add support for QMC audio
Date: Thu, 26 Jan 2023 09:32:20 +0100 [thread overview]
Message-ID: <20230126083222.374243-9-herve.codina@bootlin.com> (raw)
In-Reply-To: <20230126083222.374243-1-herve.codina@bootlin.com>
The QMC (QUICC mutichannel controller) is a controller
present in some PowerQUICC SoC such as MPC885.
The QMC audio is an ASoC component that uses the QMC
controller to transfer the audio data.
