SCMIv2.0 adds a new Reset Management Protocol to manage various reset states a given device or domain can enter. Device(s) that can be collectively reset through a common reset signal constitute a reset domain for the firmware. A reset domain can be reset autonomously or explicitly through assertion and de-assertion of the signal. When autonomous reset is chosen, the firmware is responsible for taking the necessary steps to reset the domain and to subsequently bring it out of reset. When explicit reset is chosen, the caller has to specifically assert and then de-assert the reset signal by issuing two separate RESET commands. Add the basic SCMI reset infrastructure that can be used by Linux reset controller driver.

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.
