+description:
+  The QTI BWPROF Driver is responsible for monitoring bandwidth counters on
+  Qualcomm Technologies, Inc. (QTI) chipset that represent the read/write traffic
+  through different interconnects in the system. The driver provides this data to
+  userspace clients at modest time intervals for the purpose of bandwidth
+  profiling
