Please do all RockPi4 variants into one entry, so we want something like:

      - description: Radxa ROCK Pi 4
        items:
          - enum:
              - radxa,rockpi4a
              - radxa,rockpi4b
              - radxa,rockpi4c
          - const: radxa,rockpi4
          - const: rockchip,rk3399

And as the {a,b,c} variant is the most specific it also should be the
first entry, not the second.
