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>;

				};

			};

		};
