Chander Kashyap June 18, 2013, 6:29 a.m. UTC 
In preparation of adding support for Exynos5420, which has many peripherals
similar to Exynos5250, a new common Exynos5 device tree source file is
created out of the exising Exynos5250 device tree source file. 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 SoCs. Hence
it is not possible to reuse "exynos5.dtsi" for Exynos5440.
