In case the optional dr_mode property isn't set in the dwc3 nodes the the controller will go into OTG mode iff 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 explicitely configure the dual role mode as host Signed-off-by: Sjoerd Simons <sjoerd.simons@collabora.co.uk> --- arch/arm/boot/dts/exynos5420-peach-pit.dts | 8 ++++++++ arch/arm/boot/dts/exynos5420.dtsi | 4 ++-- arch/arm/boot/dts/exynos5800-peach-pi.dts | 8 ++++++++ 3 files changed, 18 insertions(+), 2 deletions(-)
