Subject: [PATCH v8 19/20] ARM: dts: Expand the voltage range of buck1/3 regulator for exynos4412-odroidu3
Date: Fri, 08 Apr 2016 13:25:08 +0900 [thread overview]
Message-ID: <1460089509-16260-20-git-send-email-cw00.choi@samsung.com> (raw)
In-Reply-To: <1460089509-16260-1-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 - 1100 mV'.
- INT (Internal) bus frequency needs the range of '900 - 1050 mV'.
