It may be squashed with driver changes. But not with DTS changes because DTS should go through samsung-soc tree (alone). The bindings description usually go through subsystem maintainer. When sending the bindings description, please Cc at least devicetree@vger.kernel.org as mentioned by get_maintainers. It is welcomed to Cc also DT maintainers (Rob & Mark) although with simple bindings extension I think it is not a necessity. Anyway please split this and name the subject (git log --oneline arch/arm/boot/dts/exynos*: "ARM: dts: exynos: Foo Bar").
