That does not seem consistent with the purpose of LTSI.

Copying from the recent LinuxCon Japan presentation by Hisao Munakata
slides 13 and 14, code can be integrated to LTSI from:

  - upstream (several cases)
  - from SoC vendor
    - from SoC vendor tree
    - submitted upstream, still in review
    - not mainlined, chip workaround
  - from product producer, distribution
    - in-house bug-fix
    - private enhancement (with strict review)
  - others
    - not mainlined open-source project
      - ideally mainline attempt has been made
      - LTSI project will help re-attempt mainlining
    - LF / CEWG funded open project
