+description: |
+    CPUCP logging is a device that uses mailbox to collect the logs
+    generated from cpucp, and dump them into a dedicated log buffer
+    through ipc_logging framework.
+    An instance of cpucp-log should have the mailbox controller phandle and
+    addresses of log buffer set aside for this purpose.
