  Loongson-2 SoC clock control module is an integrated clock controller, which

  generates and supplies to all modules.

      - loongson,ls2k-clk

  reg:

    maxItems: 1

    description:

      The clock consumer should specify the desired clock by having the clock

      ID in its "clocks" phandle cell. See include/dt-bindings/clock/loongson,ls2k-clk.h

      for the full list of Loongson-2 SoC clock IDs.
