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 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. Changes in v5 - Add Acked-by and Reviewed-by tags. --- .../bindings/display/bridge/analogix,dp.yaml | 19 ++++++++++++++----- .../rockchip/rockchip,analogix-dp.yaml | 1 + 2 files changed, 15 insertions(+), 5 deletions(-) diff --git a/Documentation/devicetree/bindings/display/bridge/analogix,dp.yaml b/Documentation/devicetree/bindings/display/bridge/analogix,dp.yaml index 62f0521b0924..ecf206871cdd 100644 --- a/Documentation/devicetree/bindings/display/bridge/analogix,dp.yaml +++ b/Documentation/devicetree/bindings/display/bridge/analogix,dp.yaml @@ -42,13 +42,22 @@ properties: properties: port@0: $ref: /schemas/graph.yaml#/properties/port - description: - Input node to receive pixel data. + description: Input node to receive pixel data. port@1: - $ref: /schemas/graph.yaml#/properties/port - description: - Port node with one endpoint connected to a dp-connector node. + $ref: /schemas/graph.yaml#/$defs/port-base + unevaluatedProperties: false + description: Port node with one endpoint connected to sink device node. + properties: + endpoint: + $ref: /schemas/media/video-interfaces.yaml# + unevaluatedProperties: false + properties: + data-lanes: + minItems: 1 + maxItems: 4 + items: + enum: [ 0, 1, 2, 3 ] required: - port@0 diff --git a/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml b/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml index 6548f157fd96..39dafe75a680 100644 --- a/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml +++ b/Documentation/devicetree/bindings/display/rockchip/rockchip,analogix-dp.yaml @@ -160,6 +160,7 @@ examples: reg = <1>; edp_out_panel: endpoint { + data-lanes = <0 1>; remote-endpoint = <&panel_in_edp>; }; }; -- 2.34.1
