-Renesas R-Car Video Input driver (rcar_vin)
--------------------------------------------
-
-The rcar_vin device provides video input capabilities for the Renesas R-Car
-family of devices.
-
-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.
-
- - compatible: Must be one or more of the following
- - "renesas,vin-r8a7743" for the R8A7743 device
- - "renesas,vin-r8a7744" for the R8A7744 device
- - "renesas,vin-r8a7745" for the R8A7745 device
- - "renesas,vin-r8a77470" for the R8A77470 device
- - "renesas,vin-r8a774a1" for the R8A774A1 device
- - "renesas,vin-r8a774b1" for the R8A774B1 device
- - "renesas,vin-r8a774c0" for the R8A774C0 device
- - "renesas,vin-r8a7778" for the R8A7778 device
- - "renesas,vin-r8a7779" for the R8A7779 device
- - "renesas,vin-r8a7790" for the R8A7790 device
- - "renesas,vin-r8a7791" for the R8A7791 device
- - "renesas,vin-r8a7792" for the R8A7792 device
- - "renesas,vin-r8a7793" for the R8A7793 device
- - "renesas,vin-r8a7794" for the R8A7794 device
- - "renesas,vin-r8a7795" for the R8A7795 device
- - "renesas,vin-r8a7796" for the R8A7796 device
- - "renesas,vin-r8a77965" for the R8A77965 device
- - "renesas,vin-r8a77970" for the R8A77970 device
- - "renesas,vin-r8a77980" for the R8A77980 device
- - "renesas,vin-r8a77990" for the R8A77990 device
- - "renesas,vin-r8a77995" for the R8A77995 device
- - "renesas,rcar-gen2-vin" for a generic R-Car Gen2 or RZ/G1 compatible
- device.
-
- When compatible with the generic version nodes must list the
- SoC-specific version corresponding to the platform first
- followed by the generic version.
-
- - reg: the register base and size for the device registers
- - interrupts: the interrupt for the device
- - clocks: Reference to the parent clock
-
-The per-board settings for Gen2 and RZ/G1 platforms:
-
-- port - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Only the first one will be considered as each vin interface has one
- input port.
-
- - Optional properties for endpoint nodes:
- - hsync-active: see [1] for description. Default is active high.
- - vsync-active: see [1] for description. Default is active high.
- If both HSYNC and VSYNC polarities are not specified, embedded
- synchronization is selected.
- - field-active-even: see [1] for description. Default is active high.
- - bus-width: see [1] for description. The selected bus width depends on
- the SoC type and selected input image format.
- Valid values are: 8, 10, 12, 16, 24 and 32.
- - data-shift: see [1] for description. Valid values are 0 and 8.
- - data-enable-active: polarity of CLKENB signal, see [1] for
- description. Default is active high.
-
-The per-board settings for Gen3 and RZ/G2 platforms:
-
-Gen3 and RZ/G2 platforms can support both a single connected parallel input
-source from external SoC pins (port@0) and/or multiple parallel input sources
-from local SoC CSI-2 receivers (port@1) depending on SoC.
-
-- renesas,id - ID number of the VIN, VINx in the documentation.
-- ports
- - port@0 - sub-node describing a single endpoint connected to the VIN
- from external SoC pins as described in video-interfaces.txt[1].
- Describing more than one endpoint in port@0 is invalid. Only VIN
- instances that are connected to external pins should have port@0.
-
- Endpoint nodes of port@0 support the optional properties listed in
- the Gen2 per-board settings description.
-
- - port@1 - sub-nodes describing one or more endpoints connected to
- the VIN from local SoC CSI-2 receivers. The endpoint numbers must
- use the following schema.
-
- - endpoint@0 - sub-node describing the endpoint connected to CSI20
- - endpoint@1 - sub-node describing the endpoint connected to CSI21
- - endpoint@2 - sub-node describing the endpoint connected to CSI40
- - endpoint@3 - sub-node describing the endpoint connected to CSI41
-
- Endpoint nodes of port@1 do not support any optional endpoint property.
