* Omnivision OV2680 MIPI CSI-2 sensor
|
|
|
|
Required Properties:
|
|
- compatible: should be "ovti,ov2680".
|
|
- clocks: reference to the xvclk input clock.
|
|
- clock-names: should be "xvclk".
|
|
- DOVDD-supply: Digital I/O voltage supply.
|
|
- DVDD-supply: Digital core voltage supply.
|
|
- AVDD-supply: Analog voltage supply.
|
|
|
|
Optional Properties:
|
|
- reset-gpios: reference to the GPIO connected to the powerdown/reset pin,
|
|
if any. This is an active low signal to the OV2680.
|
|
|
|
The device node must contain one 'port' child node for its digital output
|
|
video port, and this port must have a single endpoint in accordance with
|
|
the video interface bindings defined in
|
|
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> (one CSI-2 lane supported).
|
|
|
|
Example:
|
|
|
|
&i2c2 {
|
|
ov2680: camera-sensor@36 {
|
|
compatible = "ovti,ov2680";
|
|
reg = <0x36>;
|
|
clocks = <&osc>;
|
|
clock-names = "xvclk";
|
|
reset-gpios = <&gpio1 3 GPIO_ACTIVE_LOW>;
|
|
DOVDD-supply = <&sw2_reg>;
|
|
DVDD-supply = <&sw2_reg>;
|
|
AVDD-supply = <®_peri_3p15v>;
|
|
|
|
port {
|
|
ov2680_to_mipi: endpoint {
|
|
remote-endpoint = <&mipi_from_sensor>;
|
|
clock-lanes = <0>;
|
|
data-lanes = <1>;
|
|
};
|
|
};
|
|
};
|
|
};
