I'm fine with using "samsung,exynos4210-g2d" for Exynos4210 though. 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). Anyway, I fine with using "samsung,exynos4212-g2d" for both. I'd like to hear Mr Kim's opinion on this as well though. > 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.

It looks good to me, please just see the two remarks above. -- Regards, Sylwester -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
