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
