Subject: [PATCH v2 0/4] ASoC: fsl: Support register and unregister rpmsg sound card through remoteproc
Date: Thu,  7 Mar 2024 16:44:33 +0900	[thread overview]
Message-ID: <20240307074437.1472593-1-chancel.liu@nxp.com> (raw)

	echo /lib/firmware/fw.elf > /sys/class/remoteproc/remoteproc0/firmware
(A)	echo start > /sys/class/remoteproc/remoteproc0/state
(B)	echo stop > /sys/class/remoteproc/remoteproc0/state

The rpmsg sound card is registered in (A) and unregistered in (B).
After "start", imx-audio-rpmsg registers devices for ASoC platform driver
and machine driver. Then sound card is registered. After "stop",
imx-audio-rpmsg unregisters devices for ASoC platform driver and machine
driver. Then sound card is unregistered.
