You missed here a lot of potential Cc. Please use get_maintainer.pl
script. It *must* be sent to devicetree list.
Please send it also to DeviceTree maintainers because you are adding
quite generic names for bindings so they may have interesting thoughts
on this.
LKML list is also missing.

I wonder whether this should be maybe "reg"?

Missing "pmc"? Where is the seventh?
This looks vendor specific, so prefix with "samsung,exynos-".

This is not bank-width? So data-width? Any vendor prefix here? How
generic is this?
These are first things which came to my mind. Maybe DT maintainers will
come with something more...
