Browse Source 
- Allow applications to interact with TA via IOCTL
  interface, with one device node per TA/token to
  allow access control policies to be enforced.
- Validate the request parameters
- Add support to to serialize request data from application
  and deserialize response from the TA
- Include process name as part of request to enable
  TA to log required info to nvlog buffer
