[PATCH v1 9/9] ARM: tegra: venice2: Add XHCI support

From: Andrew Bresticker
Date: Wed Jun 18 2014 - 02:16:51 EST


Assign ports previously owned by the EHCI controllers to the XHCI
controller. There are two external USB ports (UTMI ports 0/2 and
USB3 ports 0/1) and an internal USB port (UTMI port 1). PCIe lanes
0 and 1 are used by the USB3 ports.
