Subject[PATCH v15 1/5] arm64: dts: qcom: add data-lanes and link-freuencies into dp_out endpoint
Date
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

Changes in v7:
-- change 160000000 to 1620000000
-- separate yaml to different patch

Changes in v8:
-- correct Bjorn mail address to kernel.org

Changes in v9:
-- use symbol rate (hz) for link-frequencies at dp_out at sc7180_trogdor.dtsi

Changes in v13:
-- delete an extra space at data-lanes

Changes in v15:
-- replace space with tab at sc7180-trogdor.dtsi
