With this series we are able to initialize USB controllers using an external ULPI phy AKA USB2 on Tegra 2 devices.
This was tested to work on a Toradex Colibri T20 board, where USB2 is used to access the ASIX ethernet chipset. Testing was done with "tegra20: usb: rework set_host_mode" [1] applied. I did not spot any regressions on the UTMI ports. v2 incorporates all the review feedback I've got so far, including now trying harder to enable VBus in all configurations. Patch 3 is already in u-boot-usb and only provided as the ULPI init code now depends on it. Igor could you please take a look at Patch 4?
