Some time ago Thierry Reding sent out patches that enabled UDC on NVIDIA Tegra, unfortunately they haven't got enough traction to get into the kernel. I've rebased those patches and added a fix for the Ethernet USB Gadget on Tegra20, Marc Dietrich tested UDC driver on AC100 and Nicolas Chauvet on TK1. Like an original patchset, this series adds support for the peripheral mode only. Changelog: V2: 1) Added comments to each of patched USB Ethernet gadget models. 2) Added explanatory comment about why usb_phy_set_suspend() invocation is necessary in tegra_udc_probe(). 3) Dropped TrimSlice from patchset because it turned out that it uses USB1 controller for USB-to-SATA. 4) Moved tegra_defconfig patch before DT patches as per Stephen's suggestion. 5) Changed dr_mode to "peripheral" in DT patches since we don't support role mode switching for now.
