12description:
13  Multifunctional register block found in Tenstorrent Atlantis SoC whose main
14  function is to control clocks and resets. This block is instantiated multiple
15  times in the SoC, each block controls clock and resets for a different
16  subsystem. RCPU prcm serves low speed IO interfaces.
