Signed-off-by: Erin Lo Reviewed-by: Rob Herring --- Changes from v3: - No change. Changes from v2: - No change. I realized that for this patch series, there's no need to add anything under the mt8183-scp node (neither the mt8183-rpmsg or the cros-ec-rpmsg) for them to work, since mt8183-rpmsg is added directly as a rproc_subdev by code, and cros-ec-rpmsg is dynamically created by SCP name service.
