From 1056a273ec2ce4446e38598c08ef782bbfe9bdc3 Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Thu, 5 Feb 2015 00:35:58 +0900 Subject: [PATCH] ARM: dts: add eMMC reset line for exynos5422-odroidxu3 This patch adds reset-gpios property to the eMMC slot, so the MMC driver is able to properly reset eMMC card on system restart and thus fixes system hang on software reboot.
