* Sony IMX290 1/2.8-Inch CMOS Image Sensor
The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with
Square Pixel for Color Cameras. It is programmable through I2C and 4-wire
interfaces. The sensor output is available via CMOS logic parallel SDR output,
Low voltage LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the
default. No bindings have been defined for the other busses.
Required Properties:
- compatible: Should be "sony,imx290"
- reg: I2C bus address of the device
- clocks: Reference to the xclk clock.
- clock-names: Should be "xclk".
- clock-frequency: Frequency of the xclk clock in Hz.
- vdddo-supply: Sensor digital IO regulator.
- vdda-supply: Sensor analog regulator.
- vddd-supply: Sensor digital core regulator.
Optional Properties:
- reset-gpios: Sensor reset GPIO
The imx290 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.
Required Properties on endpoint:
- data-lanes: check ../video-interfaces.txt
- link-frequencies: check ../video-interfaces.txt
- remote-endpoint: check ../video-interfaces.txt
Example:
&i2c1 {
...
imx290: camera-sensor@1a {
compatible = "sony,imx290";
reg = <0x1a>;
reset-gpios = <&msmgpio 35 GPIO_ACTIVE_LOW>;
pinctrl-names = "default";
pinctrl-0 = <&camera_rear_default>;
clocks = <&gcc GCC_CAMSS_MCLK0_CLK>;
clock-names = "xclk";
clock-frequency = <37125000>;
vdddo-supply = <&camera_vdddo_1v8>;
vdda-supply = <&camera_vdda_2v8>;
vddd-supply = <&camera_vddd_1v5>;
port {
imx290_ep: endpoint {
data-lanes = <1 2 3 4>;
link-frequencies = /bits/ 64 <445500000>;
remote-endpoint = <&csiphy0_ep>;
};
};
};
