[PATCH v1 8/9] ARM: tegra: jetson-tk1: Add XHCI support

From: Andrew Bresticker
Date: Wed Jun 18 2014 - 02:17:33 EST


Assign USB ports previously owned by the EHCI controllers to the XHCI
controller. There is a mini-PCIe USB port (UTMI port 1) and a USB A
connector (UTMI port 2, USB3 port 0). PCIe lane 0 is used for USB3
port 0.
