[PATCH v2 0/3] drm/exynos: rotator: Add support for s5pv210

[Paweł Chmiel]

This patchset adds support for s5pv210 soc, into 
Samsung DRM Rotator driver. Currently only NV12 and XRGB8888 formats
 are supported.

It was tested by using simple tool from 
https://www.spinics.net/lists/linux-samsung-soc/msg60498.html

Changes from v1:
  - fixed order of chipsets in documentation and removed ordering
    from it
