Subject: [U-Boot] [PATCH 0/3] Support eMMC reset using DT for some exynos boards
Date: Thu, 08 Jan 2015 14:44:12 +0900 [thread overview]
Message-ID: <54AE192C.2000302@samsung.com> (raw)
This patchset is to support eMMC reset using DT for some exynos boards
e.g. Odroid X2/U3/XU3.
It needs to reset eMMC memory to perform complete reboot, so we should
handle SD4_nRESET_OUT line specially. SD4_nRESET_OUT line is connected
to gpio and it can have different gpio by boards, so we will get gpio
from DT.
This patchset based on http://git.denx.de/u-boot-dm.git gpio-working
branch.
Thanks.
