This series adds support for xHCI on NVIDIA Tegra SoCs.  This includes:
 - patches 1, 2, and 3: minor cleanups for mailbox framework and xHCI,
 - patches 4 and 5: adding a driver for the mailbox used to communicate
   with the xHCI controller's firmware,
 - patches 6 and 7: extending the XUSB pad controller driver to support
   the USB PHY types (UTMI, HSIC, and USB3),
 - patches 8 and 9: adding a xHCI host-controller driver, and
 - patches 10, 11, and 12: updating the relevant DT files.

The mailbox driver (patch 5) has a compile-time dependency on patch 2 and
a run-time dependency on patch 3.  Both the PHY (patch 7) and host (patch 9)
drivers have compile-time dependencies on the mailbox driver.  The host
driver also has a run-time dependency on patch 1.  Because of this, this
entire series should probably go through the Tegra tree.

Why shouldn't I pick 2 & 3 at least?
