Since MFC v7 support was added for Exynos5420 and Exynos3250 SoC with same compatible string "samsung,mfc-v7". As both SoCs having different hardware properties and having same compatible string for both SoCs doesn't seems to be correct. Add a new compatible to differentiate the two SoC's MFC IP, at the same time to keep git bisect happy, add a fallback to mfc-v7 for Exynos3250. Changes since v3: - Addressed review comments from Krzysztof Kozlowski. - Added new compatible string for Exynos3250 followed by mfc-v7 fallback. Changes since v2: - Addressed review comments from Krzysztof Kozlowski. - Changed subject prefixes matching the subsystem. Changes since v1: - Addressed review comments from Marek Szyprowski. - Changed subject prefix from arm64 to arm. - Addressed review comments from Krzysztof Kozlowski. - Changed subject prefixes matching the subsystem. - Added new compatible string for Exynos3250 followed by mfc-v7 fallback. - Removed checkpatch warnings from s5p_mfc.c.Sent separate patch series for the same. - Addressed review comments from Tommaso Merciai. - Change in commit message body from used to use in Patch-2.
