Secure Proxy is another communication scheme in Texas Instrument's devices intended to provide an unique communication path from various processors in the System on Chip(SoC) to a central System Controller. Secure proxy is, in effect, an evolution of current generation Message Manager hardware block found in K2G devices. However the following changes have taken place: Secure Proxy instance exposes "threads" or "proxies" which is primary representation of "a" communication channel. Each thread is preconfigured by System controller configuration based on SoC usage requirements. Secure proxy by itself represents a single "queue" of communication but allows the proxies to be independently operated. Each Secure proxy thread can uniquely have their own error and threshold interrupts allowing for more fine control of IRQ handling. Provide the driver support for Secure Proxy and thread instances. NOTE: Secure proxy configuration is only done by System Controller, hence these are assumed to be pre-configured instances.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
