Lane mapping is mainly used for below scenarios: 1. Correct PCB lane swap and differential line routing crossover without hardware changes; 2. Adapt mismatched lane pin definitions between SoC and eDP panel; 3. Support multiple panel hardware variants on the same board by configuring data-lanes in device tree only. Additionally, add data-lanes setting in Rockchip eDP DT node example to show actual lane mapping usage. Acked-by: Conor Dooley Reviewed-by: Sebastian Reichel Reviewed-by: Luca Ceresoli Signed-off-by: Damon Ding --- Changes in v2: - Add lane mapping application scenarios in commit message. - Remove redundant deprecated property 'data-lanes' for eDP node. - Update port@1 $ref to /schemas/graph.yaml#/$defs/port-base. Changes in v3: - Squash data-lanes adjustment of Rockchip eDP DT example into this commit. - Add unevaluatedProperties: false to both the port@1 and endpoint nodes.
