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. Changes from v1: - s/SD4_nRESET_OUT/nRESET_OUT - Remove codes for non DT case - Add comments about eMMC reset delay time Joonyoung Shim (3): samsung: board: support eMMC reset using DT Odroid: Add eMMC-reset node on DT Odroid-XU3: Add eMMC-reset node on DT arch/arm/dts/exynos4412-odroid.dts | 5 +++++ arch/arm/dts/exynos5422-odroidxu3.dts | 5 +++++ board/samsung/common/board.c | 28 ++++++++++++++++++++++++++++ board/samsung/odroid/odroid.c | 8 -------- doc/device-tree-bindings/exynos/emmc-reset.txt | 15 +++++++++++++++ 5 files changed, 53 insertions(+), 8 deletions(-) create mode 100644 doc/device-tree-bindings/exynos/emmc-reset.txt
