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>; ++ }; ++ }; ++ }; |
