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.
This patchset is based on the Kukjin's dt-exynos tree. (git://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git v3.12-next/dt-exynos)
Changes from v2: - Remove unnecessary 'of_match_ptr' - Consolidate dt support code and documentation into one patch - Fix typo and remove status node.
Changes from v1: - Added exynos5250 binding. - Move limit table into driver code from DT-nodes

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 of input picture. Each SoCs has slightly different limit value compared with any others. For example, exynos4210's max_size of RGB888 is 16k x 16k. But, others have 8k x 8k. Another example the exynos5250 should have multiple of 2 pixel size for its X/Y axis. Thus, we should keep different tables for each of them. This patch also includes desciptions of each nodes for the rotator and specifies a example how to bind it.
