   4 Subject: [PATCH 294/423] drm/vc4: Recognize a more specific compatible string
   5  for V3D.
   6
   7 The Raspberry Pi Foundation's firmware updates are shipping device
   8 trees using the old string, so we'll keep recognizing that as this rev
   9 of V3D.  Still, we should use a more specific name in the upstream DT
  10 to clarify which board is being supported, in case we do other revs of
  11 V3D in the future.
