* Sony 1/4.0-Inch 8Mpixel CMOS Digital Image Sensor
The Sony imx219 is a 1/4.0-inch CMOS active pixel digital image sensor with
an active array size of 3280H x 2464V. It is programmable through I2C
interface. The I2C address is fixed to 0x10 as per sensor data sheet.
Image data is sent through MIPI CSI-2, which is configured as either 2 or 4
data lanes.
Required Properties:
- compatible: value should be "sony,imx219" for imx219 sensor
- reg: I2C bus address of the device
- clocks: reference to the xclk input clock.
- clock-names: should be "xclk".
- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
- AVDD-supply: Analog voltage supply, 2.8 volts
- DVDD-supply: Digital core voltage supply, 1.2 volts
Optional Properties:
- xclr-gpios: reference to the GPIO connected to the xclr pin, if any. Must be
released after all supplies are applied.
This is an active high signal to the imx219.
The imx219 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 2>, or <1 2 3 4> (two or four lane CSI-2
supported)
Example:
sensor@10 {
compatible = "sony,imx219";
reg = <0x10>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&imx219_clk>;
clock-names = "xclk";
xclr-gpios = <&gpio_sensor 0 0>;
DOVDD-supply = <&vgen4_reg>; /* 1.8v */
AVDD-supply = <&vgen3_reg>; /* 2.8v */
DVDD-supply = <&vgen2_reg>; /* 1.2v */
imx219_clk: camera-clk {
compatible = "fixed-clock";
#clock-cells = <0>;
clock-frequency = <24000000>;
};
port {
sensor_out: endpoint {
remote-endpoint = <&csiss_in>;
clock-lanes = <0>;
data-lanes = <1 2>;
};
};
};
