Hello Krzysztof,
you can also add the node to the exynos4412-odroid-common dtsi. I have
checked that it works properly on an X2.
Thanks for patches and fixing that alignment issue!
With best wishes,
Tobias

Thanks for testing it. I'll send a follow up with you as Tested-by.
I didn't add it because my Odroid U3 is in unusable state... I need to
fix it.
