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

+(cherry picked from commit 90d7116061f86c1f8ea460806a0414addea7b58b)
