+description:
+  Multifunctional register block found in Tenstorrent Atlantis SoC whose main
+  function is to control clocks and resets. This block is instantiated multiple
+  times in the SoC, each block controls clock and resets for a different
+  subsystem. RCPU prcm serves low speed IO interfaces.
