 Gentle ping for merging this in v4.1-next...
 
OK, I'll queue this into v4.1-next/mach-samsung.

Just note, some newer SoC has different poweroff scheme not just using PS_HOLD
based so maybe we need to revisit the poweroff later ;-)

Thanks,
Kukjin

I'd say that this is even a candidate for 4.0.0. Like I reported 
earlier, the SoC gets really hot without proper shutdown, so definitely 
something you don't want for a not properly cooled system (U3 without 
the fan running e.g.).


With best wishes,
Tobias

Tested on my Odroid-X2 and it seems to solve the 'heating issue' when
the system is shut down but left on the AC adapter.
