Are there going to be more controllers that are compatible with
"ls7a-gpio"? If not, you can simplify both of these to have 2 const:
entries, like:

      - items:
          - const: loongson,ls2k1000-gpio
          - const: loongson,ls2k-gpio

      - items:
          - const: loongson,ls7a1000-gpio
          - const: loongson,ls7a-gpio

Either way,

Thanks for sticking at this one :)
