Because this is a carrier board this should probably be something like:

  compatible = "luckfox,omni3576", "luckfox,core3576", "rockchip,rk3576";

And this .dts-file should be split up into something like:
- rk3576-luckfox-core3576.dtsi for parts related to the Core3576 SoM
- rk3576-luckfox-omni3576.dts for parts only related to the carrier board

Jonas
