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 (Tegra20), Nicolas Chauvet on TK1 (Tegra124) and Michał Mirosław on TF300T (Tegra30). Like an original patchset, this series adds support for the peripheral mode only. Changelog: V6: 1) Moved 'SKB reserve' quirk setup from f_ncm to u_uther as per Felipe's suggestion. V5: 1) Moved of_device_get_match_data() above clock enabling to not leave clock enabled in case of error. The SoC data matching function shouldn't ever fail, but let's assume that it could for consistency. V4: 1) Used of_device_get_match_data() instead of of_match_node() to cleanup code a tad. V3: 1) Specified platform flags directly in the SoC info as per Michał's suggestion. 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.
