The "apps_smmu" on the Qualcomm sdm845 platform is an implementation of the SMMU-500, that consists of a single TCU (Translation Control Unit) and multiple TBUs (Translation Buffer Units). These TBUs have hardware debugging features that are specific and only present on Qualcomm hardware. Represent them as independent DT nodes. List all the resources that are needed to operate them (such as registers, clocks, power domains and interconnects).

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 reStructuredText 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.
