SCMI protocols in the platform can optionally signal to the OSPM agent the expected execution latency for a specific resource/operation pair. Introduce an SCMI system wide optional property to describe a global time threshold which can be configured on a per-platform base to determine the opportunity, or not, for an SCMI command advertised to have a higher latency than the threshold, to be considered for atomic operations: high-latency SCMI synchronous commands should be preferably issued in the usual non-atomic mode.

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.
