Subject: [PATCH v1 40/50] ARM: dts: exynos: change parent and rate of
 bus_gen in Exynos5422

The bus_gen OPP table has been aligned to the new parent rate. This patch
sets the proper parent and picks the init frequency before the devfreq
governor starts working. It sets also parent rate (MPLL to 600MHz).
