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