From 6d365ea0acf0b6d8e4efd28d9853d287c52d7fec Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Mon, 1 Oct 2012 00:44:35 +0200 Subject: tegra20: add USB ULPI init code This adds the required code to set up a ULPI USB port. It is mostly a port of the Linux ULPI setup code with some tweaks added for more correctness, discovered along the way of debugging this. To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT have to be set in the board configuration file.
