Actually, the fix is slightly less obvious, mostly because I introduced
a bug while converting the code to stacked domains. I noticed that
something was amiss in the Exynos code, but fixed it the wrong way
(I assumed the DT was wrong, while it was the code).
Now, in the light of ace283a04a4a, the fix should be:

Jason, any chance you could apply this on top of be42c9ea7b5f? We'll still
have a conflict when the two branches get merged, but at least we'll know
what the resolution is.
Thanks,
