Move data-lanes property from mdss_dp node to dp_out endpoint. Also
add link-frequencies property into dp_out endpoint as well. The last
frequency specified at link-frequencies will be the max link rate
supported by DP.

Changes in v5:
-- revert changes at sc7180.dtsi and sc7280.dtsi
-- add &dp_out to sc7180-trogdor.dtsi and sc7280-herobrine.dtsi

Changes in v6:
-- add data-lanes and link-frequencies to yaml

Separate patch. Also you didn't check the get_maintainers output, so required parties were not included into the distribution.

Also as you'd check the get_maintainers output, please fix other email addresses too.

No. Use $ref for both of them.

No, they are not required.

deprecation of old data-lanes property?
there is no old data-lanes property.

There is one:

$ grep -n data-lanes Documentation/devicetree/bindings/display/msm/dp-controller.yaml
82:  data-lanes:
