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. if ARM_SCMI_PROTOCOL config ARM_SCMI_HAVE_TRANSPORT bool help This declares whether at least one SCMI transport has been configured.
