Yes.
I'll support the suspend-to-ram for Exynos5433. But it is not right now.
because the current kernel support the suspend-to-ram for only 32-bit Exynos.
and the pm/suspend code are included in in arch/arm/mach-exynos/.

To support the suspend-to-ram for 64bit Exynos, I need a lot of time
to support the 64-bit suspend.
