+description: |
+  The Bus Clock Manager (BCM) is a dedicated hardware accelerator that manages
+  shared system resources by aggregating requests from multiple Resource State
+  Coordinators (RSC). Interconnect providers are able to vote for aggregated
+  thresholds values from consumers by communicating through their respective
+  RSCs.

+  compatible:
+    enum:

+
+  qcom,tcs-wait:
+    description: |
+      Optional mask of which TCSs (Triggered Command Sets) wait for completion
+      upon triggering. If not specified, then the AMC and WAKE sets wait for
+      completion. The mask bits are available in the QCOM_ICC_TAG_* defines.
+
+      The AMC TCS is triggered immediately when icc_set_bw() is called. The
+      WAKE/SLEEP TCSs are triggered when the RSC transitions between active and
+      sleep modes.
+
+      In most cases, it's necessary to wait in both the AMC and WAKE sets to
+      ensure resources are available before use. If a specific RSC and its use
+      cases can ensure sufficient delay by other means, then this can be
+      overridden to reduce latencies.
