+ The System Management Controller (SMC) on Apple Silicon machines is a
+ piece of hardware that exposes various functionalities such as
+ temperature sensors, voltage/power meters, shutdown/reboot handling,
+ GPIOs and more.
+
+ Communication happens via a shared mailbox using the RTKit protocol
+ which is also used for other co-processors. The SMC protocol then
+ allows reading and writing many different keys which implement the
+ various features. The MFD core device handles this protocol and
+ exposes it to the sub-devices.
