* 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>;
			};
		};
	};
