Thanks your feedback, I do my homework. Do you mean following modify ?

properties:
  compatible:
    oneOf:
add oneOf Keep following enum 
      - enum:
          - aspeed,ast2400-sdhci
          - aspeed,ast2500-sdhci
          - aspeed,ast2600-sdhci
And add following items 
      - items:
          - const: aspeed,ast2700-sdhci
          - const: aspeed,ast2600-sdhci
