Audio Support Rock Pi S

I am trying to get I2S output working, but need some help with the right device tree overlay.
For now, I enable i2s_8ch_xx for example, but not getting to far with this overlay:

// For ROCK Pi S
/dts-v1/;
/plugin/;

/ {
  model = "Radxa ROCK Pi S";
	compatible = "radxa,rockpis-rk3308", "rockchip,rk3308";

  fragment@0 {
    target = <&i2s_8ch_0>;
    __overlay__ {
      status = "okay";
      };
  };
};

Any pointers?
PS: I know there is no codec loaded, will tackle that at stage 2. :slight_smile:
