Since S5PV210 is the first SoC with the g2d IP as used on exynos4210, I am inclined to use "samsung,s5pv210-g2d" for exynos4210. This was suggested by Kukjin Kim as well. > For instance for tegra SoCs a conventions like "nvidia,tegra<chip>-<ip>", > is used (e.g. "nvidia,tegra20-gr2d"). > >> For exynos4x12 SoCs, >> compatible = "samsung,exynos4212-g2d" > > I'm not sure how well exynos4212 is going to be supported in the kernel. > As Mr Park pointed out, if it is going to be nearly not existent then we > could perhaps go with "samsung,exynos4412-g2d" for Exynos4412 and > "samsung,exynos4212-g2d" for Exynos4212 (as needed).

I will use "samsung,exynos4212-g2d" for now as it has dtsi reference, although there is no exclusive board support based on this SoC. > >> For exynos5250, 5410 (In case of Exynos5440, I'm not sure that the SoC >> has same ip) >> compatible = "samsung,exynos5250-g2d" >> >> To other guys, >> The device tree is used by not only v4l2 side but also drm side so we >> should reach an arrangement.
