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>; + }; + }; + };
