Qualcomm TEE (QTEE) hosts Trusted Applications (TAs) and services in the secure world, accessed via objects. A QTEE client can invoke these objects to request services. Similarly, QTEE can request services from the nonsecure world using objects exported to the secure world. Add low-level primitives to facilitate the invocation of objects hosted in QTEE, as well as those hosted in the nonsecure world. If support for object invocation is available, the qcom_scm allocates a dedicated child platform device. The driver for this device communicates with QTEE using low-level primitives.

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.
