+      Parameters in the form of opaque key/value pairs that are to be sent to the SIO
+      coprocesssor once it boots. These parameters can point into the reserved memory
+      regions (in device address space).
+
+      Note that unlike Apple's firmware, we treat the parameters, and the data they
+      refer to, as opaque. Apple embed short data blobs into their SIO devicetree node
+      that describe the DMA-enabled peripherals (presumably with defined semantics).
+      Their driver processes those blobs and sets up data structure in mapped device
+      memory, then references this memory in the parameters sent to the SIO. At the
+      level of description we are opting for in this binding, we assume the job of
+      constructing those data structures has been done in advance, leaving behind an
+      opaque list of key/value parameter pairs to be sent by a prospective driver.
+
+      This approach is chosen for two reasons:
+
+       - It means we don't need to try to understand the semantics of Apple's blobs
+         as long as we know the transformation we need to do from Apple's devicetree
+         data to SIO data (which can be shoved away into a loader). It also means the
+         semantics of Apple's blobs (or of something to replace them) need not be part
+         of the binding and be kept up with Apple's firmware changes in the future.
+
+       - It leaves less work for the driver attaching on this binding. Instead the work
+         is done upfront in the loader which can be better suited for keeping up with
+         Apple's firmware changes.

+title: Apple SMC Hardware Monitoring
+
+description:
+  Apple's System Management Controller (SMC) exposes a vast array of
+  hardware monitoring sensors, including temperature probes, current and
+  voltage sense, power meters, and fan speeds. It also provides endpoints
+  to manually control the speed of each fan individually. Each Apple
+  Silicon device exposes a different set of endpoints via SMC keys. This
+  is true even when two machines share an SoC. The CPU core temperature
+  sensor keys on an M1 Mac mini are different to those on an M1 MacBook
+  Pro, for example.
