Do you mean like this:
--------
sound {
compatible = "rockchip,rk3399-max98357a-rt5514-da7219";

dailink-0 {
compatible = "rockchip,rk3399-max98357a";
rockchip,cpu = <&i2s0>;
rockchip,codec = <&max98357a>;
};

dailink-1 {
compatible = "rockchip,rk3399-rt5514";
rockchip,cpu = <&i2s0>;
rockchip,codec = <&headsetcodec>;
};

dailink-2 {
compatible = "rockchip,rk3399-da7219";
rockchip,cpu = <&i2s0>;
rockchip,codec = <&codec>;
};
};
--------
Above, the machine drvier will handle them. Please correct me if I 
misunderstand.

Thanks.
