+STMicroelectronics Remote Processor
+-----------------------------------
+
+This binding provides support for adjunct processors found on ST SoCs.
+
+The remote processors can be controlled from the bootloader or the primary OS.
+If the bootloader starts a remote processor processor the primary OS must detect
+its state and act accordingly.
+
+The node name is significant, as it defines the name of the CPU and the name
+of the firmware to load: "rproc-<name>-fw".
This business about the firmware name describes a behavior of Linux's
core remoteproc code and seems out of place in a binding document.
Agreed, will remove.
