* Omnivision OV7740 CMOS image sensor
|
|
The Omnivision OV7740 image sensor supports multiple output image
|
size, such as VGA, and QVGA, CIF and any size smaller. It also
|
supports the RAW RGB and YUV output formats.
|
|
The common video interfaces bindings (see video-interfaces.txt) should
|
be used to specify link to the image data receiver. The OV7740 device
|
node should contain one 'port' child node with an 'endpoint' subnode.
|
|
Required Properties:
|
- compatible: "ovti,ov7740".
|
- reg: I2C slave address of the sensor.
|
- clocks: Reference to the xvclk input clock.
|
- clock-names: "xvclk".
|
|
Optional Properties:
|
- reset-gpios: Rreference to the GPIO connected to the reset_b pin,
|
if any. Active low with pull-ip resistor.
|
- powerdown-gpios: Reference to the GPIO connected to the pwdn pin,
|
if any. Active high with pull-down resistor.
|
|
Endpoint node mandatory properties:
|
- remote-endpoint: A phandle to the bus receiver's endpoint node.
|
|
Example:
|
|
i2c1: i2c@fc028000 {
|
ov7740: camera@21 {
|
compatible = "ovti,ov7740";
|
reg = <0x21>;
|
pinctrl-names = "default";
|
pinctrl-0 = <&pinctrl_sensor_power &pinctrl_sensor_reset>;
|
clocks = <&isc>;
|
clock-names = "xvclk";
|
assigned-clocks = <&isc>;
|
assigned-clock-rates = <24000000>;
|
reset-gpios = <&pioA 43 GPIO_ACTIVE_LOW>;
|
powerdown-gpios = <&pioA 44 GPIO_ACTIVE_HIGH>;
|
|
port {
|
ov7740_0: endpoint {
|
remote-endpoint = <&isc_0>;
|
};
|
};
|
};
|
};
