  19 +* Infineon irs1125 time of flight sensor
  20 +
  21 +The Infineon irs1125 is a time of flight digital image sensor with
  22 +an active array size of 352H x 286V. It is programmable through I2C
  23 +interface. The I2C address defaults to 0x3D, but can be reconfigured
  24 +to address 0x3C or 0x41 via I2C commands. Image data is sent through
  25 +MIPI CSI-2, which is configured as either 1 or 2 data lanes.
  26 +
  27 +Required Properties:
  28 +- compatible: value should be "infineon,irs1125" for irs1125 sensor
  29 +- reg: I2C bus address of the device
  30 +- clocks: reference to the xclk input clock.
  31 +- pwdn-gpios: reference to the GPIO connected to the reset pin.
  32 +             This is an active low signal to the iirs1125.
  33 +
  34 +The irs1125 device node should contain one 'port' child node with
  35 +an 'endpoint' subnode. For further reading on port node refer to
  36 +Documentation/devicetree/bindings/media/video-interfaces.txt.
  37 +
  38 +Endpoint node required properties for CSI-2 connection are:
  39 +- remote-endpoint: a phandle to the bus receiver's endpoint node.
  40 +- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
  41 +- data-lanes: should be set to <1> or <1 2> (one or two lane CSI-2
  42 +  supported)
  43 +
  44 +Example:
  45 +       sensor@10 {
  46 +               compatible = "infineon,irs1125";
  47 +               reg = <0x3D>;
  48 +               #address-cells = <1>;
  49 +               #size-cells = <0>;
  50 +               clocks = <&irs1125_clk>;
  51 +               pwdn-gpios = <&gpio 5 0>;
  52 +
  53 +               irs1125_clk: camera-clk {
  54 +                       compatible = "fixed-clock";
  55 +                       #clock-cells = <0>;
  56 +                       clock-frequency = <26000000>;
  57 +               };
  58 +
  59 +               port {
  60 +                       sensor_out: endpoint {
  61 +                               remote-endpoint = <&csiss_in>;
  62 +                               clock-lanes = <0>;
  63 +                               data-lanes = <1 2>;
  64 +                       };
  65 +               };
  66 +       };
