dmprovider.service

I was bothered by a large amount of logs like this appearing in syslog, and it stopped when I stopped dmprovider.service.
What kind of service is this?

hello @shizimi, 

these are the logs for device management service, your tinker board r2.0 shall stop printing related logs once dmprovider.service is stopped.
