Subject: [PATCH v3 7/7] ASoC: dt-bindings: imx-rpmsg: Add binding doc for rpmsg machine driver
Date: Thu, 25 Feb 2021 10:52:43 +0800 [thread overview]
Message-ID: <1614221563-26822-8-git-send-email-shengjiu.wang@nxp.com> (raw)
In-Reply-To: <1614221563-26822-1-git-send-email-shengjiu.wang@nxp.com>
Imx-rpmsg is a new added machine driver for supporting audio on Cortex-M
core. The Cortex-M core will control the audio interface, DMA and audio
codec, setup the pipeline, the audio driver on Cortex-A core side is just
to communitcate with M core, it is a virtual sound card and don't touch
the hardware.
