Subject: [PATCH v2 1/2] ARM: dts: exynos: Move bus related OPPs to the
boards DTS
Currently the only Exynos5422-based boards that support bus frequency
scaling are Hardkernel's Odroid XU3/XU4/HC1. Move the bus related OPPs to
the boards DTS, because those OPPs heavily depend on the clock topology
and top PLL rates, which are being configured by the board's bootloader.
