Cover letter [U-Boot] [PATCH v2 0/3] Support eMMC reset using DT for some exynos boards
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 nRESET_OUT line specially. nRESET_OUT line is connected to gpio and it can have different gpio by boards, so we will get gpio from DT.
This patchset is based on http://git.denx.de/u-boot-dm.git gpio-working branch.
Thanks.
