Hello Julien,
  Thanks for the feedback. I shall modify it accordingly.

The .compatible is exynos5410_dt_compat which lists
"samsung,exynos5410". Hence, I wanted to make the whole PLATFORM
platform specific to the exynos5410.
Now, rethinking what you have said, I believe as all of this is
generic code, the  .compatible should then be exynos5_dt_compat, thus:
PLATFORM_START(exynos5, "SAMSUNG EXYNOS5")
    .compatible = exynos5_dt_compat,
and not, .compatible = exynos5410_dt_compat as it is now.

I believe this is what you were suggesting? In which case when more
SoCs are added, we just add the corresponding string in
exynos5_dt_compat. Would that be the correct interpretation?

Hence, if a SoC needs something platform specific, we then add a new
PLATFORM_START for that particular SoC.

I hope I am following you guys correctly here!
Thanks as always
- Suriyan
