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