+description: |
+  The PolarFire SoC system controller is communicated with via a mailbox.
+  This binding represents several of the functions provided by the system
+  controller which do not belong in a specific subsystem, such as reading
+  the fpga device certificate, all of which follow the same format:
+    - a command + optional payload sent to the sys controller
+    - a status + a payload returned to Linux.
