Only the common nodes required for basic boot up on EXYNOS5420 based boards are moved into this new file and the rest of the common nodes would be moved subsequently. EXYNOS5440 SoC is quite different from EXYNOS5250 and EXYNOS5420. Hence it is not possible to reuse "exynos5.dtsi" for EXYNOS5440.

We lose our capability to set the rate of and enable a clock through debugfs. This is ok though because the debugfs features are mainly used for testing and development of new clock code. To maintain compatibility with the original MSM clock code we make a wrapper for clk_reset() that calls the struct msm_clk specific reset function. This is necessary for the usb and sdcc devices on MSM until a better suited API is made available.
