From e1c69efc52bbad7fa289694672d467ab4fdf9f52 Mon Sep 17 00:00:00 2001 From: Sjoerd Simons Date: Thu, 25 Sep 2014 17:32:14 +0900 Subject: [PATCH] ARM: dts: Explicitly set dr_mode on exynos Peach boards In case the optional dr_mode property isn't set in the dwc3 nodes the the controller will go into OTG mode if both USB host and USB gadget functionality are enabled in the kernel configuration. Unfortunately this results in USB not working on exynos5420-peach-pit and exynos5800-peach-pi with such a kernel configuration unless manually change the mode. To resolve that explicitly configure the dual role mode as host.
