1* Omnivision OV7670 CMOS sensor 2 3The Omnivision OV7670 sensor supports multiple resolutions output, such as 4CIF, SVGA, UXGA. It also can support the YUV422/420, RGB565/555 or raw RGB 5output formats. 6 7Required Properties: 8- compatible: should be "ovti,ov7670" 9- clocks: reference to the xclk input clock. 10- clock-names: should be "xclk". 11 12Optional Properties: 13- reset-gpios: reference to the GPIO connected to the resetb pin, if any. 14 Active is low. 15- powerdown-gpios: reference to the GPIO connected to the pwdn pin, if any. 16 Active is high. 17 18The device node must contain one 'port' child node for its digital output 19video port, in accordance with the video interface bindings defined in 20Documentation/devicetree/bindings/media/video-interfaces.txt. 21 22Example: 23 24 i2c1: i2c@f0018000 { 25 ov7670: camera@21 { 26 compatible = "ovti,ov7670"; 27 reg = <0x21>; 28 pinctrl-names = "default"; 29 pinctrl-0 = <&pinctrl_pck0_as_isi_mck &pinctrl_sensor_power &pinctrl_sensor_reset>; 30 reset-gpios = <&pioE 11 GPIO_ACTIVE_LOW>; 31 powerdown-gpios = <&pioE 13 GPIO_ACTIVE_HIGH>; 32 clocks = <&pck0>; 33 clock-names = "xclk"; 34 assigned-clocks = <&pck0>; 35 assigned-clock-rates = <25000000>; 36 37 port { 38 ov7670_0: endpoint { 39 remote-endpoint = <&isi_0>; 40 }; 41 }; 42 }; 43 }; 44
