		Renesas R-Car MIPI CSI-2
		------------------------

		The R-Car CSI-2 receiver device provides MIPI CSI-2 capabilities for the
		Renesas R-Car and RZ/G2 family of devices. It is used in conjunction with the
		R-Car VIN module, which provides the video capture capabilities.

		Mandatory properties
		--------------------
		- compatible: Must be one or more of the following
		- "renesas,r8a774a1-csi2" for the R8A774A1 device.
		- "renesas,r8a774b1-csi2" for the R8A774B1 device.
		- "renesas,r8a774c0-csi2" for the R8A774C0 device.
		- "renesas,r8a7795-csi2" for the R8A7795 device.
		- "renesas,r8a7796-csi2" for the R8A7796 device.
		- "renesas,r8a77965-csi2" for the R8A77965 device.
		- "renesas,r8a77970-csi2" for the R8A77970 device.
		- "renesas,r8a77980-csi2" for the R8A77980 device.
		- "renesas,r8a77990-csi2" for the R8A77990 device.

		- reg: the register base and size for the device registers
		- interrupts: the interrupt for the device
		- clocks: A phandle + clock specifier for the module clock
		- resets: A phandle + reset specifier for the module reset

		The device node shall contain two 'port' child nodes according to the
		bindings defined in Documentation/devicetree/bindings/media/
		video-interfaces.txt. port@0 shall connect to the CSI-2 source. port@1
		shall connect to all the R-Car VIN modules that have a hardware
		connection to the CSI-2 receiver.

		- port@0- Video source (mandatory)
		- endpoint@0 - sub-node describing the endpoint that is the video source

		- port@1 - VIN instances (optional)
		- One endpoint sub-node for every R-Car VIN instance which is connected
		to the R-Car CSI-2 receiver.

		Example:

		csi20: csi2@fea80000 {
		compatible = "renesas,r8a7796-csi2";
		reg = <0 0xfea80000 0 0x10000>;
		interrupts = <0 184 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&cpg CPG_MOD 714>;
		power-domains = <&sysc R8A7796_PD_ALWAYS_ON>;
		resets = <&cpg 714>;

		ports {
		#address-cells = <1>;
		#size-cells = <0>;

		port@0 {
		#address-cells = <1>;
		#size-cells = <0>;

		reg = <0>;

		csi20_in: endpoint@0 {
		reg = <0>;
		clock-lanes = <0>;
		data-lanes = <1>;
		remote-endpoint = <&adv7482_txb>;
		};
		};

		port@1 {
		#address-cells = <1>;
		#size-cells = <0>;

		reg = <1>;

		csi20vin0: endpoint@0 {
		reg = <0>;
		remote-endpoint = <&vin0csi20>;
		};
		csi20vin1: endpoint@1 {
		reg = <1>;
		remote-endpoint = <&vin1csi20>;
		};
		csi20vin2: endpoint@2 {
		reg = <2>;
		remote-endpoint = <&vin2csi20>;
		};
		csi20vin3: endpoint@3 {
		reg = <3>;
		remote-endpoint = <&vin3csi20>;
		};
		csi20vin4: endpoint@4 {
		reg = <4>;
		remote-endpoint = <&vin4csi20>;
		};
		csi20vin5: endpoint@5 {
		reg = <5>;
		remote-endpoint = <&vin5csi20>;
		};
		csi20vin6: endpoint@6 {
		reg = <6>;
		remote-endpoint = <&vin6csi20>;
		};
		csi20vin7: endpoint@7 {
		reg = <7>;
		remote-endpoint = <&vin7csi20>;
		};
		};
		};
		};
