      Microchip PolarFire clock control (CLKCFG) is an integrated clock controller,
      which gates and enables all peripheral clocks.
    
      This device tree binding describes 33 gate clocks.  Clocks are referenced by
      user nodes by the CLKCFG node phandle and the clock index in the group, from
      0 to 32.

              clock config registers:
              These registers contain enable, reset & divider tables for the, cpu,
              axi, ahb and rtc/mtimer reference clocks as well as enable and reset
              for the peripheral clocks.

          The clock consumer should specify the desired clock by having the clock
          ID in its "clocks" phandle cell. See include/dt-bindings/clock/microchip,mpfs-clock.h
          for the full list of PolarFire clock IDs.
