Commit 90d7116061f8 ("drm/vc4: Recognize a more specific compatible string for V3D.") added "brcm,bcm2835-v3d" in v4.6 and kept the original one around, because the Raspberry Pi firmware was shipping device trees that used it. That string was never part of the binding: the documentation added in commit 4653f22e9ab0 ("dt-bindings: Add binding docs for V3D.") describes only "brcm,bcm2835-v3d", and no upstream device tree has ever used "brcm,vc4-v3d": the first in-tree V3D node, from commit 49ac67e0c39c ("ARM: bcm2835: Add VC4 to the device tree."), already carried the specific name. The firmware device trees the compatible was kept for predate v4.6, released in 2016. Drop it from both match tables.
