Each VIN instance has a single parallel input that supports RGB and YUV video, with both external synchronization and BT.656 synchronization for the latter. Depending on the instance the VIN input is connected to external SoC pins, or on Gen3 and RZ/G2 platforms to a CSI-2 receiver. properties: compatible: oneOf: - items: - enum: - renesas,vin-r8a7742 # RZ/G1H - renesas,vin-r8a7743 # RZ/G1M - renesas,vin-r8a7744 # RZ/G1N - renesas,vin-r8a7745 # RZ/G1E - renesas,vin-r8a77470 # RZ/G1C - renesas,vin-r8a7790 # R-Car H2 - renesas,vin-r8a7791 # R-Car M2-W - renesas,vin-r8a7792 # R-Car V2H - renesas,vin-r8a7793 # R-Car M2-N - renesas,vin-r8a7794 # R-Car E2 - const: renesas,rcar-gen2-vin # Generic R-Car Gen2 or RZ/G1 - items: - enum: - renesas,vin-r8a774a1 # RZ/G2M - renesas,vin-r8a774b1 # RZ/G2N - renesas,vin-r8a774c0 # RZ/G2E - renesas,vin-r8a774e1 # RZ/G2H - renesas,vin-r8a7778 # R-Car M1 - renesas,vin-r8a7779 # R-Car H1 - renesas,vin-r8a7795 # R-Car H3 - renesas,vin-r8a7796 # R-Car M3-W - renesas,vin-r8a77961 # R-Car M3-W+ - renesas,vin-r8a77965 # R-Car M3-N - renesas,vin-r8a77970 # R-Car V3M - renesas,vin-r8a77980 # R-Car V3H - renesas,vin-r8a77990 # R-Car E3 - renesas,vin-r8a77995 # R-Car D3 - renesas,vin-r8a779a0 # R-Car V3U reg: maxItems: 1 interrupts: maxItems: 1 clocks: maxItems: 1 power-domains: maxItems: 1 resets: maxItems: 1 #The per-board settings for Gen2 and RZ/G1 platforms: port: $ref: /schemas/graph.yaml#/$defs/port-base unevaluatedProperties: false description: A node containing a parallel input properties: endpoint: $ref: video-interfaces.yaml# unevaluatedProperties: false properties: hsync-active: description: If both HSYNC and VSYNC polarities are not specified, embedded synchronization is selected. default: 1 vsync-active: description: If both HSYNC and VSYNC polarities are not specified, embedded synchronization is selected. default: 1 field-active-even: true bus-width: true data-shift: true data-enable-active: description: Polarity of CLKENB signal default: 1 pclk-sample: true data-active: true #The per-board settings for Gen3 and RZ/G2 platforms: renesas,id: description: VIN channel number $ref: /schemas/types.yaml#/definitions/uint32 minimum: 0 maximum: 31 ports: $ref: /schemas/graph.yaml#/properties/ports properties: port@0: $ref: /schemas/graph.yaml#/$defs/port-base unevaluatedProperties: false description: Input port node, single endpoint describing a parallel input source. properties: endpoint: $ref: video-interfaces.yaml# unevaluatedProperties: false properties: hsync-active: description: If both HSYNC and VSYNC polarities are not specified, embedded synchronization is selected. default: 1 vsync-active: description: If both HSYNC and VSYNC polarities are not specified, embedded synchronization is selected. default: 1 field-active-even: true bus-width: true data-shift: true data-enable-active: description: Polarity of CLKENB signal default: 1 pclk-sample: true data-active: true port@1: $ref: /schemas/graph.yaml#/properties/port description: Input port node, multiple endpoints describing all the R-Car CSI-2 modules connected the VIN. properties: endpoint@0: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to CSI20. endpoint@1: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to CSI21. endpoint@2: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to CSI40. endpoint@3: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to CSI41. anyOf: - required: - endpoint@0 - required: - endpoint@1 - required: - endpoint@2 - required: - endpoint@3 port@2: $ref: /schemas/graph.yaml#/properties/port description: Input port node, multiple endpoints describing all the R-Car ISP modules connected the VIN. properties: endpoint@0: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to ISP0. endpoint@1: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to ISP1. endpoint@2: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to ISP2. endpoint@3: $ref: /schemas/graph.yaml#/properties/endpoint description: Endpoint connected to ISP3. required: - compatible - reg - interrupts - clocks - power-domains allOf: - if: not: properties: compatible: contains: enum: - renesas,vin-r8a7778 - renesas,vin-r8a7779 then: required: - resets - if: properties: compatible: contains: enum: - renesas,vin-r8a7778 - renesas,vin-r8a7779 - renesas,rcar-gen2-vin then: required: - port else: required: - renesas,id - ports additionalProperties: false examples: # Device node example for Gen2 platform - | #include #include #include vin1: vin@e6ef1000 { compatible = "renesas,vin-r8a7790", "renesas,rcar-gen2-vin";
