[U-Boot] [PATCH 0/3] Tegra 2 USB ULPI series

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"
applied. I did not spot any regressions on the UTMI ports.

Patchset is based on top of u-boot-tegra/next

Lucas Stach (3):
  tegra20: complete periph_id enum
  tegra20: add clock_set_pllout function
  tegra20: add USB ULPI init code
