This series adds support for xHCI on NVIDIA Tegra SoCs.  This includes:
  - adding a driver for the mailbox used to communicate with the xHCI
    controller's firmware,
  - extending the XUSB pad controller driver to support the USB PHY
    types (UTMI, HSIC, and USB3), and
  - adding a xHCI host-controller driver.

Can you please remind us what dependencies exist between the patches? In
other words, is it possible to apply parts of the series to their usual
subsystem branches, or does the whole thing need to go into a single topic
branch in order to avoid compile-time problems, or run-time problems in
features unrelated to the new functionality? Thanks.

The whole thing will probably need to go into one branch.  Patch 4/9
("pinctrl: tegra-xusb: Add USB PHY support") has compile-time
dependencies on patch 2/9 ("mailbox: Add NVIDIA Tegra XUSB mailbox
driver") and patch 6/9 ("usb: xhci: Add NVIDIA Tegra xHCI
host-controller driver") has compile-time dependencies on both patches
2/9 and 4/9.
