This protocol allows an agent to start, stop a CPU or set reset vector. It
is used to manage auxiliary CPUs in an LM (e.g. additional cores in an AP
cluster).

Add Logical Machine Management(LMM) protocol which is intended for boot,
shutdown, and reset of other logical machines (LM). It is usually used to
allow one LM to manager another used as an offload or accelerator engine.

Using the pattern 'scmi-protocol-0x<PROTO_ID>-<VEND_ID>' as MODULE_ALIAS
allows the SCMI core to autoload this protocol, if built as a module, when
its protocol operations are requested by an SCMI driver.

i.MX95 System Manager(SM) firmware includes a SCMI vendor protocol, SCMI
MISC protocol which includes controls that are misc settings/actions that
must be exposed from the SM to agents. They are device specific and are
usually define to access bit fields in various mix block control modules,
IOMUX_GPR, and other General Purpose registers, Control Status Registers
owned by the SM.

i.MX95 has a battery-backed module(BBM), which has persistent storage
(GPR), an RTC, and the ON/OFF button. The System Manager(SM) firmware
use SCMI vendor protocol(SCMI BBM) to let agent be able to use GPR, RTC
and ON/OFF button.
