And the rinato dts file we posted to mainline has the > compatible string. model = "Samsung Rinato board"; compatible = "samsung,rinato-rev05", "samsung,exynos3250", "samsung,exynos3"; The problem is "samsung,exynos3" because the patch solves only issue on multiplatform kernel run on non-exynos board.
