• deprecate rpmsg_virtio_set_status and rpmsg_virtio_get_status, virtio API should be used instead.

New APIs:

• rpmsg:

  • Add new rpmsg_ept_release_cb to inform application that a endpoint has been released.

• virtio rpmsg:

  • rpmsg_virtio_get_rx_buffer_sizeand rpmsg_get_rx_buffer_size: get the RPMsg buffer payload size.

• virtio:

  • wait_notified ops to implement specific action in virtio transport layer waiting new TX free buffer.
