This patchset includes dt support for exynos rotator. The exynos4 platform is only dt-based since 3.10, we should convert driver data and ids to dt-based parsing methods. The rotator driver has a limit table to get size limit. The minimum size of RGB888 format is 8 x 8 and maximum size is 8K x 8K. The other format, YCbCr420 2-Plane has 32 x 32 min size and 32K x 32K max size. Each format should be multiple of 'align' value.
