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

Commit Message

Andrew Bresticker June 18, 2014, 6:16 a.m. UTC

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.
