Some Coresight devices that kernel don't have permission to access or configure. For these devices, a dummy driver is needed to register them as Coresight devices. The module may also be used to define components that may not have any programming interfaces, so that paths can be created in the driver. It provides Coresight API for operations on dummy devices, such as enabling and disabling them. It also provides the Coresight dummy sink/source paths for debugging.

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.
