This series adds support for xHCI on NVIDIA Tegra SoCs.  This includes:
 - patches 1 and 2: adding a driver for the mailbox used to communicate
   with the xHCI controller's firmware,
 - patches 3 and 4: extending the XUSB pad controller driver to support
   the USB PHY types (UTMI, HSIC, and USB3),
 - patches 5 and 6: adding a xHCI host-controller driver, and
 - patches 7, 8, and 9: updating the relevant DT files.

The PHY and host drivers have compile-time dependencies on the mailbox
driver, and the host driver has compile-time dependencies on the PHY
driver.  It is probably best if these all get merged through the Tegra
tree.  This series still needs ACKs from the relevant maintainers for
the mailbox and xHCI host drivers and their device-tree bindings.

Tested on Venice2, Jetson TK1, and Big with a variety of USB2.0 and
USB3.0 memory sticks and ethernet dongles using controller firmware
recently posted by Andrew Chew [0].

Based on v3.18-rc2.  All other dependencies (xHCI modules and mailbox
series) have been merged.

I do not feel comfortable enough with xHCI to give a reviewed-by tag,
but FWIW I have found nothing wrong with these patches.
