I would not mind comments on parent patch and some help here.

Basically I tried to work around limitation in 

int serdev_device_add(struct serdev_device *serdev)
{
...
       /* Only a single slave device is currently supported. */
       if (ctrl->serdev) {
...
                   return -EBUSY;

Best regards,
