+description:
+  Cx ipeak HW module is used to limit the current drawn by various subsystem
+  blocks on Cx power rail. Each client needs to set their bit in tcsr register
+  if it is going to cross its own threshold. If all clients are going to cross
+  their thresholds then Cx ipeak hw module will raise an interrupt to cDSP block
+  to throttle cDSP's fmax.
