* 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>;
|
