    Subject[PATCH v3 19/20] ARM: dts: Expand the voltage range of buck1/3 regulator for exynos4412-odroidu3
    Date
    This patch expands the voltage range of buck1/3 regulator due to as following:
    - MIF (Memory Interface) bus frequency needs the range of '900 - 1050 mV'.
    - INT (Internal) bus frequency needs the range of '900 - 1000 mV'.
