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

     25    description: |
     26      Optional mask of which TCSs (Triggered Command Sets) wait for completion
     27      upon triggering. If not specified, then the AMC and WAKE sets wait for
     28      completion. The mask bits are available in the QCOM_ICC_TAG_* defines.
     29
     30      The AMC TCS is triggered immediately when icc_set_bw() is called. The
     31      WAKE/SLEEP TCSs are triggered when the RSC transitions between active and
     32      sleep modes.
     33
     34      In most cases, it's necessary to wait in both the AMC and WAKE sets to
     35      ensure resources are available before use. If a specific RSC and its use
     36      cases can ensure sufficient delay by other means, then this can be
     37      overridden to reduce latencies.
