Hey Kukjin,
Hi, Sorry for late response...
It's been almost a month since I posted the first iteration of this patchset on the list, with only trivial cosmetic changes and an addition of a similar fix for Arndale Octa boards. Do you feel it needs more review from specific folks before pulling it in or ? Seems a bit of a shame if this would fail to make it for 3.18 (one could even argue the dt patches are 3.17 RC material!) as it fixes USB functionality being broken depending on the kernel configuration used.

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 adds similar updates for Arndale Octa as reported by Andreas Färber. Last patch enables gadget mode in the default exynos config to more easily catch/trigger issues like these. I suspect the Samsung SMDK5420 DTS might need similar changes, so it would be great if users of those board could verify this.
