Subject: [PATCHv4 2/6] ARM: dts: exynos: fix regulator min values of LDO13 for Odroid XU3/XU4
Date: Sat, 22 Sep 2018 07:52:34 +0000 [thread overview]
Message-ID: <20180922075238.884-4-linux.amoon@gmail.com> (raw)
In-Reply-To: <20180922075238.884-1-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.
