          RTC_MATCH, asserted when the content of the Alarm register is equal
          to that of the RTC's count register.

  clocks:
    items:
      - description: |
          AHB clock
      - description: |
          Reference clock: divided by the prescaler to create a time-based
          strobe (typically 1 Hz) for the calendar counter. By default, the rtc
          on the PolarFire SoC shares it's reference with MTIMER so this will
          be a 1 MHz clock.
