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 + };
