Hello Marek,

I've tested the patchset on 4.7-rc7 and noticed that it breaks reboot on
my ODROID-X2.

Going to check where exactly things break.
Sadly it's the last patch where everything comes together:
"iommu/exynos: Add proper runtime pm support"

I still have to check if forcing runpm status to 'on' makes a
difference. I suspect that the aggressive clock gating might be the
reason?
Thanks for testing. I will check this issue. Could you send me your
.config?
This is the config I'm currently using:
https://github.com/tobiasjakobi/odroid-environment/blob/master/sourcecode/system/vanilla-4.7-debug.conf

Do you think checking this with no_console_suspend makes sense?

- Tobias
