From the initial commit message of the DRM code: "The G2D is a 2D graphic accelerator that supports Bit Block Transfer. This G2D driver is exynos drm specific and supports only G2D(version 4.1) of later Exynos series from Exynos4X12 because supporting DMA." (https://git.kernel.org/cgit/linux/kernel/git/stable/linux-stable.git/commit/drivers/gpu/drm/exynos/exynos_drm_g2d.c?id=d7f1642c90ab5eb2d7c48af0581c993094f97e1a) In fact, this doesn't even mention the Exynos5?!
