	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.

Chancel Liu (4):
  ASoC: fsl: imx_pcm_rpmsg: Register component with rpmsg channel name
  ASoC: fsl: imx-audio-rpmsg: Register device with rpmsg channel name
  ASoC: fsl: Let imx-audio-rpmsg register platform device for card
  ASoC: fsl: imx-rpmsg: Update to correct DT node
