you're adding two boards (beta and retail) and as they are not compatible to 
each other (see gpio differences), they should also have their own compatible 
properties, so something like:

- Firefly Firefly-RK3288 board:
    Required root node properties:
      - compatible = "firefly,firefly-rk3288", "rockchip,rk3288";
    or
      - compatible = "firefly,firefly-rk3288-beta", "rockchip,rk3288";

and this differentiation should of course also happen in the dts files themself.
