Subject: [PATCH v4 19/20] ARM: dts: Expand the voltage range of buck1/3 regulator for exynos4412-odroidu3
Date: Mon, 14 Dec 2015 15:38:23 +0900	[thread overview]
Message-ID: <1450075104-13705-20-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1450075104-13705-1-git-send-email-cw00.choi@samsung.com>

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'.
