Document DU found in RZ/G2UL SoC. The DU block is identical to RZ/G2L SoC, but has only DPI interface. While at it, add missing required property port@1 for RZ/G2L and RZ/V2L SoCs. Currently there is no user for the DPI interface and hence there won't be any ABI breakage for adding port@1 as required property for RZ/G2L and RZ/V2L SoCs. Acked-by: Conor Dooley <conor.dooley@xxxxxxxxxxxxx> Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx> --- v3->v4: * Restored the ports property for RZ/G2UL and described port@0 for the DPI interface. * Restored tags from Geert and Conor as the change is trivial (Replaced port 1->0 from v2). v2->v3: * Replaced ports->port property for RZ/G2UL as it supports only DPI. and retained ports property for RZ/{G2L,V2L} as it supports both DSI and DPI output interface. * Added missing blank line before example. * Dropped tags from Conor and Geert as there are new changes. v1->v2: * Updated commit description related to non ABI breakage. * Added Ack from Conor. --- .../bindings/display/renesas,rzg2l-du.yaml | 32 +++++++++++++++++-- 1 file changed, 29 insertions(+), 3 deletions(-) diff --git a/Documentation/devicetree/bindings/display/renesas,rzg2l-du.yaml b/Documentation/devicetree/bindings/display/renesas,rzg2l-du.yaml index 08e5b9478051..95e3d5e74b87 100644 --- a/Documentation/devicetree/bindings/display/renesas,rzg2l-du.yaml +++ b/Documentation/devicetree/bindings/display/renesas,rzg2l-du.yaml @@ -18,6 +18,7 @@ properties: compatible: oneOf: - enum: + - renesas,r9a07g043u-du # RZ/G2UL - renesas,r9a07g044-du # RZ/G2{L,LC} - items: - enum: @@ -60,9 +61,6 @@ properties: $ref: /schemas/graph.yaml#/properties/port unevaluatedProperties: false - required: - - port@0 - unevaluatedProperties: false renesas,vsps: @@ -88,6 +86,34 @@ required: additionalProperties: false +allOf: + - if: + properties: + compatible: + contains: + const: renesas,r9a07g043u-du + then: + properties: + ports: + properties: + port@0: + description: DPI + + required: + - port@0 + else: + properties: + ports: + properties: + port@0: + description: DSI + port@1: + description: DPI + + required: + - port@0 + - port@1 + examples: # RZ/G2L DU - | -- 2.43.0
