Although Kukjin picked Exynos 5433 ARM64 patches but they were not
accepted upstream by arm-soc. He rolled it for few releases but:
1. Reason for not accepting by arm-soc was not resolved - there is no DTS.
2. Kukjin did not rebase the branch for 4.4... which maybe means that he
wants to drop it?
3. Anyone (but me...) can send Galaxy Note4 (Exynos5433) DTS file based
on sources on opensource.samsung.com. The DTS there is for 32-bit but it
can be probably easily adjusted for ARM64.
All of this means that Device Tree support for this driver can't be
merged now and effort for mainlining 5433 may be unfortunately wasted...
