		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.
