+ ARM System Control and Management Interface (SCMI) protocol is a
+ set of operating system-independent software interfaces that are
+ used in system management. SCMI is extensible and currently provides
+ interfaces for: Discovery and self-description of the interfaces
+ it supports, Power domain management which is the ability to place
+ a given device or domain into the various power-saving states that
+ it supports, Performance management which is the ability to control
+ the performance of a domain that is composed of compute engines
+ such as application processors and other accelerators, Clock
+ management which is the ability to set and inquire rates on platform
+ managed clocks and Sensor management which is the ability to read
+ sensor data, and be notified of sensor value.
+
+ This protocol library provides interface for all the client drivers
+ making use of the features offered by the SCMI.
