What are the differences between DWC OTG hardware and OTG hardware found
in s3c64xx/s5pc100/s5pv210 and Exynos4 SoCs series? I've did a brief look
at register definitions and most of them looks same. Can this driver be
merged with s3c-hsotg.c driver?

Does it mean that HID or mass-storage (both host or gadget drivers) needs
modifications to get them working with this DWC OTG driver?
