Rpmsg channel for MICFIL can also be created through rpmsg name service announcement. If this driver is probed, Cortex-A can access MICFIL which is actually controlled by Cortex-M through rpmsg channel for MICFIL. This driver also helps register ASoC platform device thus use of PLATFORM_DEVID_AUTO macro in API can automatically create device for each rpmsg channel.
