Add support for the XUSB pad controller found on Tegra186 SoCs. It is mostly similar to the same IP found on earlier chips, but the number of pads exposed differs, as do the programming sequences. Note that the DVDD_PEX, DVDD_PEX_PLL, HVDD_PEX and HVDD_PEX_PLL power supplies of the XUSB pad controller require strict power sequencing and are therefore controlled by the PMIC on Tegra186.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
