Subject[PATCH v4 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'.
