Thank you for clarifying. I’ve updated the patch to move
hdmi_connector out of the root node and reference it using
&hdmi_connector instead of defining it under &{/} like below:

git diff arch/arm64/boot/dts/qcom/talos-evk-lvds-auo,g133han01.

Could you please confirm if this change aligns with your
expectation.
