I am not sure of this. The only samsung specific code in dw_mmc-pltfm.c file is the data for of_device_id instances. The clock lookup added into this file in the 3rd patch does not cause any harm on non-samsung SoC's which might not define those clocks (on clock lookup failure, there are only warning printed, the driver's probe does not fail. I would prefer not to add separate file for Exynos SoC's for now. Splitting into different files will need to defined new callbacks which I fell is not really required.
