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-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 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: type: object description: A node containing a parallel input with a single endpoint definitions as documented in Documentation/devicetree/bindings/media/video-interfaces.txt properties: endpoint: type: object 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 remote-endpoint: true required: - remote-endpoint additionalProperties: false additionalProperties: false #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: 15 ports: type: object description: A node containing input nodes with endpoint definitions as documented in Documentation/devicetree/bindings/media/video-interfaces.txt properties: port@0: type: object description: Input port node, single endpoint describing a parallel input source. properties: reg: const: 0 endpoint: type: object 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 remote-endpoint: true required: - remote-endpoint additionalProperties: false required: - endpoint additionalProperties: false port@1: type: object description: Input port node, multiple endpoints describing all the R-Car CSI-2 modules connected the VIN. properties: '#address-cells': const: 1 '#size-cells': const: 0 reg: const: 1 endpoint@0: type: object description: Endpoint connected to CSI20. properties: reg: const: 0 remote-endpoint: true required: - reg - remote-endpoint additionalProperties: false endpoint@1: type: object description: Endpoint connected to CSI21. properties: reg: const: 1 remote-endpoint: true required: - reg - remote-endpoint additionalProperties: false endpoint@2: type: object description: Endpoint connected to CSI40. properties: reg: const: 2 remote-endpoint: true required: - reg - remote-endpoint additionalProperties: false endpoint@3: type: object description: Endpoint connected to CSI41. properties: reg: const: 3 remote-endpoint: true required: - reg - remote-endpoint additionalProperties: false anyOf: - required: - endpoint@0 - required: - endpoint@1 - required: - endpoint@2 - required: - endpoint@3 additionalProperties: false required: - compatible - reg - interrupts - clocks - power-domains - 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 <dt-bindings/clock/r8a7790-cpg-mssr.h> #include <dt-bindings/interrupt-controller/arm-gic.h> #include <dt-bindings/power/r8a7790-sysc.h> vin1: vin@e6ef1000 { compatible = "renesas,vin-r8a7790", "renesas,rcar-gen2-vin";
