Allen, this won't work :-(
Check Documentation/devicetree/bindings/media/mediatek,vcodec-subdev-decoder.yaml
...the schema requires vcodec-lat@[0-9a-f] and vcodec-core@[0-9a-f].

If you want to call them all video-codec@addr, you have to also fix the schema.

P.S.: Did you try to run `make dtbs_check`?

Regards,
Angelo
