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.



properties:

  compatible:

    enum:

      - tenstorrent,atlantis-prcm-rcpu



  reg:

    maxItems: 1



  clocks:

    maxItems: 1



  "#clock-cells":

    const: 1

    description:

      See <dt-bindings/clock/tenstorrent,atlantis-prcm-rcpu.h> for valid indices.



  "#reset-cells":

    const: 1



required:

  - compatible

  - reg

  - clocks

  - "#clock-cells"
