Like a lot of things used in device trees of ARM platforms, since we did
not have any proper processes defined for creating device tree bindings
and device trees themselves, including any recommended set of good
practices.
We are now trying to define all of this and so it's time to rethink all
the DT related things that has been added for ARM platforms since the time
DT for ARM was introduced and make sure that everything is reasonable.

Still, I think this patch can go as is and node naming can be fixed in
separate patches, including any other quirks of Exynos device trees.
