ls3c5000l, ls3c5000, ls3d5000, ls3a6000 and ls3c6000 are compatible with 
ls3a5000.

Can i write compatible string this way:

properties:
  compatible:
    oneOf:
      - enum:
          - loongson,ls3a5000-mc-edac
      - items:
          - enum:
              - loongson,ls3c5000l-mc-edac
              - loongson,ls3c5000-mc-edac
              - loongson,ls3d5000-mc-edac
              - loongson,ls3a6000-mc-edac
              - loongson,ls3c6000-mc-edac
          - const: loongson,ls3a5000-mc-edac
