Along with clock-output-names? Hmm, it should be safe to move it there. By specifying this property or not we can control whether the I2S clocks are exposed or not. If we move it to exynos5250.dtsi the clocks we always be exposed. But should be the right thing to do anyway. I will post v3. Of course we recently made the clock-output-names property deprecated, it will not bee needed any more. It was there just to ensure the clk names are unique.

This patch adds new cpu, codec subnodes according to the updated "google,snow-audio-max98095" DT bindings and the I2S clock tree configuration so sound on the HDMI interface can also be supported.
