The patch looks OK to me, I'm fine with it being merged via Kukjin's tree
due to the dts dependencies (including other pending dts patches touching
the arch/arm/boot/dts/exynos5420.dtsi file).
I think we need also Mike ACK for that, I could also queue the patch for
the clk tree and create a topic branch, but merging both patches via
arm-soc seems a more sane option in this case.
