All Exynos SoCs have the same syscon reboot and poweroff device nodes so
there is no need to duplicate the same on each SoC dtsi and can be moved
to a common dtsi that can be included by all the SoCs dtsi files.

Hello,
The patch was tested on an Exynos5800 Peach Pi Chromebook and an
Exynos5422 Odroid XU4 board. Reboot and poweroff worked for both.
But testing on Exynos3 and Exynos4 will be highly appreciated.
Best regards,
Javier

Would you be so kind and add my suggested-by (since it comes from
https://wiki.tizen.org/wiki/Exynos_Mainline_Kernel_TODO :) )
I'll test it on Exynos4 at work and then apply... but few comments below:

In some of the DTSI this was under "soc" node, not at top-level.
Unfortunately we do not have consistency here - some DTSI have "soc",
some not. Anyway I think we should move to "soc" version.

Just to keep it consistent and logic - include after skeleton.

Yes, I noticed this but as you said not all DTSI have a soc node
and that's why I made it top level in the DTSI.

Not sure I'm following, did you mean to do it as a follow up or
to add a soc node for the missing DTSI as a part of this series?

Ok, for include I usually try to keep alphabetically sorted but
I'll move it after skeleton if you prefer to keep it consistent.

I meant to send a v2 with this under "soc" node even though on some DTS
we do not have the "soc". Optional follow up would be to make DTS
consistent and move nodes under "soc"... but that would be also a lot of
churn.

Thanks for the clarification. I'll post a v2 then moving under a soc node.
