Subject: [PATCH 3/7] ASoC: dt-bindings: fsl_rpmsg: Add binding doc for rpmsg cpu dai driver
Date: Fri, 5 Feb 2021 14:57:26 +0800 [thread overview]
Message-ID: <1612508250-10586-4-git-send-email-shengjiu.wang@nxp.com> (raw)
In-Reply-To: <1612508250-10586-1-git-send-email-shengjiu.wang@nxp.com>
fsl_rpmsg cpu dai driver is dummy driver, which is mainly used for
getting the user's configuration from device tree and configure the
clocks which is used by Cortex-M core. So in this document define the
needed property.
