++* Infineon irs1125 time of flight sensor
++
++The Infineon irs1125 is a time of flight digital image sensor with
++an active array size of 352H x 286V. It is programmable through I2C
++interface. The I2C address defaults to 0x3D, but can be reconfigured
++to address 0x3C or 0x41 via I2C commands. Image data is sent through
++MIPI CSI-2, which is configured as either 1 or 2 data lanes.
++
++Required Properties:
++- compatible: value should be "infineon,irs1125" for irs1125 sensor
++- reg: I2C bus address of the device
++- clocks: reference to the xclk input clock.
++- pwdn-gpios: reference to the GPIO connected to the reset pin.
++	      This is an active low signal to the iirs1125.
++
++The irs1125 device node should contain one 'port' child node with
++an 'endpoint' subnode. For further reading on port node refer to
++Documentation/devicetree/bindings/media/video-interfaces.txt.
++
++Endpoint node required properties for CSI-2 connection are:
++- remote-endpoint: a phandle to the bus receiver's endpoint node.
++- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
++- data-lanes: should be set to <1> or <1 2> (one or two lane CSI-2
++  supported)
++
++Example:
++	sensor@10 {
++		compatible = "infineon,irs1125";
++		reg = <0x3D>;
++		#address-cells = <1>;
++		#size-cells = <0>;
++		clocks = <&irs1125_clk>;
++		pwdn-gpios = <&gpio 5 0>;
++
++		irs1125_clk: camera-clk {
++			compatible = "fixed-clock";
++			#clock-cells = <0>;
++			clock-frequency = <26000000>;
++		};
++
++		port {
++			sensor_out: endpoint {
++				remote-endpoint = <&csiss_in>;
++				clock-lanes = <0>;
++				data-lanes = <1 2>;
++			};
++		};
++	};
