As of commitc7289b1c8a("arm64: tegra: Enable SMMU support on Tegra194"), SMMU support is enabled system-wide on Tegra194. However, there was a bit of overlap between the SMMU enablement and the USB support addition, so the USB device tree nodes are missing the iommus and interconnects properties. This in turn leads to SMMU faults for these devices, since by default the ARM SMMU will fault. Add the iommus and interconnects properties to the XUSB and XUDC device tree nodes to restore their functionality.

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.
