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