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 -- To unsubscribe from this list: send the line unsubscribe linux-samsung-soc in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Best regards 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.).

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.
