When building a kernel with support for both USB host and USB Gadget support on the dwc3 controller on the Exynos5 soc will go into USB OTG mode unless otherwise specified in the dtb, which is unhelpful for boards hooked up to run as USB host.
First patch in this set explicitely set the dual-role mode for the dwc3 controller on Peach pi and Peach pit boards to host mode. Second patch enables gadget mode in the default exynos config to more easily catch/trigger issues like these. I suspect other boards base using exynos5420/5800 might need the similar fixes (Arndale Octa and Samsung SMDK5420) to their dts files, so would be great if folks with those board could verify this.
