Hmm.... I wonder why you changed this. Sysmmu rotator and rotator are
not a part of LCD power domain on Exynos4x12 (or they should not be?)? Why?
On Exynos 4210 rotator (and its SYSMMU) belongs to LCD0 power domain. On
Exynos 4x12 it belong to TOP power domain (which is always on and not
described in DTS).
Best regards
