This patchset includes device tree support for rotator of exynos4210/4x12/5250. Unfortunately, each of them has slightly different limitations of image size. The rotator can support several image formats(RGB888/555, YCbCr422/420_2/3p). For convinience, however, exynos drm rotator driver only support RGB888 and YCbCr420 2-Plane formats. For example, the exynos4210 has 16k x 16k maximum size . But rest of them has 8k x 8k. In addition, RGB888 X/Y pixel size of exynos5250 should be multiple of 2. But others are multiple of 4. Thus, we should define different compatibles and limit tables for each chipsets.
