+* 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>;
+ };
+ };
+ };
