From aa8e00fab5e65a07c2cae52274946a908805ea60 Mon Sep 17 00:00:00 2001 From: Joonyoung Shim Date: Thu, 15 Jan 2015 11:45:56 +0900 Subject: samsung: board: support eMMC reset using DT Some exynos boards require special handling of nRESET_OUT line for eMMC memory to perform complete reboot e.g. Odroid X2/U3/XU3 boards. This will support eMMC reset using DT from reset_misc of samsung common board file.
