To increase the flexibility of supporting different DP main link configuration at different platform, add both data-lanes and link-frequencies property into endpoint so that different platform can specify its own main link combination of both data lanes and max supported link rate. Changes in v7: -- split yaml out of dtsi patch -- link-frequencies from link rate to symbol rate -- deprecation of old data-lanes property Changes in v8: -- correct Bjorn mail address to kernel.org Changes in v10: -- add menu item to data-lanes and link-frequecnis Changes in v11: -- add endpoint property at port@1 Changes in v12: -- use enum for item at data-lanes and link-frequencies Changes in v13: -- revised changes at port@0 -- use correct ref schemas for both port@0 and port@1 -- mark both port@0 and port@1 are required -- add line between data-lanes and link-frequencies properties Changes in v14: -- add "unevaluatedProperties: false: to endpoint at port@1 -- remove unnecessary quote to $ref -- re store "$ref: /schemas/graph.yaml#/properties/port" to port@0 Changes in v15: -- re store desciption of port@0 Signed-off-by: Kuogee Hsieh <quic_khsieh@quicinc.com> --- .../bindings/display/msm/dp-controller.yaml | 25 +++++++++++++++++++++- 1 file changed, 24 insertions(+), 1 deletion(-)
