tegra: usb: Add support for Tegra USB peripheral
This adds basic support for the Tegra2 USB controller. Board files should
call board_usb_init() to set things up.
Configuration is performed through the FDT, with aliases used to set the
order of the ports, like this fragment:
aliases {
/* This defines the order of our USB ports */
usb0 = "/usb@0xc5008000";
usb1 = "/usb@0xc5000000";
};
