Why are you adding a new property as deprecated? Why does this duplicate
what you're adding to the port node? At the very least, your commit is
lacking an explanation.

Thank you for the review.
I referenced the implementation in
Documentation/devicetree/bindings/display/msm/dp-controller.yaml. After
evaluating QCOM DP driver and other drivers, I agree that implementing
'data-lanes' in the endpoint node is the preferred and common approach
nowadays.
The top-level `data-lanes` property together with the `deprecated` mark
was leftover content from my early reference and arrangement, which I
neglected to delete before submitting. It is redundant, unreasonable and
should not have been added at all.
I will fix it in the next version.
Best regards,
Damon
