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).

You are mapping size of > 0x1000 instead of 0x64. Any particular reason? (it does not really > matter... just wondering) Nope, it might be just a copy/paste issue I've missed. Do you want to unify it to 0x64 or 0x1000?
