-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 {
