+
+description:
+  Qualcomm QMI based TMD cooling device(s) are used for various mitigations for
+  remote subsystem(s) including remote processor mitigation, rail voltage
+  restriction etc. Some devices such as "cpuv_restriction_cold" are for warming,
+  (e.g. by raising minimum voltage on core system rails).
+
+  Each subnode represents a control for a single instance of the TMD service running
+  on a remote subsystem.
