Subject: [PATCHv5 2/6] ARM: dts: exynos: fix regulator min values of LDO13 for Odroid XU3/XU4
Date: Thu, 27 Sep 2018 14:07:34 +0000 [thread overview]
Message-ID: <20180927140738.1006-3-linux.amoon@gmail.com> (raw)
In-Reply-To: <20180927140738.1006-1-linux.amoon@gmail.com>
Looking at the schematic sd_2 min/max range from 1.8V/2.8V so fix the
regulator min value to 1.8V. Without these changes sdcard will failed
to detect on booting when UHS-I tuning is enabled.
