Just to make it clear, Marek's signed-off should appear for one of
conditions:
- he contributed some source code to your patch,
- he took your patch, rebased, send by himself (not a case here, I
think),
- he contributed significant ideas, although for this there is a
"Co-developed-by" tag.
If someone made just review - add Reviewed-by. If someone suggested the
patch - add Suggested-by.

Thanks Maciej for working on this.
I am trying to make the names more consistent:
1. For Exynos bindings:
Samsung Exynos SoC xxx yyy zzz
2. For multiple SoCs (S3C, S5P, Exynos etc):
Samsung SoC xxx yyy zzz
Currently the names are mixture of legacy and new names. It is a
nit-pick but makes all bindings look like a part of bigger effort, not
bunch of patches done by random people. :)
If there are no objections, maybe you could change it to:
Samsung SoC Image Rotator

The comments are duplicating the compatible, so skip them.

Skip the description. Clocks property is a well-known binding.

I think there is no need to maxItems since all possible items are fixed.
