[U-Boot] [PATCH 0/3] Support eMMC reset using DT for some exynos boards

[Joonyoung Shim]

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.
