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