* OV2659 1/5-Inch 2Mp SOC Camera
The Omnivision OV2659 is a 1/5-inch SOC camera, with an active array size of
1632H x 1212V. It is programmable through a SCCB. The OV2659 sensor supports
multiple resolutions output, such as UXGA, SVGA, 720p. It also can support
YUV422, RGB565/555 or raw RGB output formats.
Required Properties:
- compatible: Must be "ovti,ov2659"
- reg: I2C slave address
- clocks: reference to the xvclk input clock.
- clock-names: should be "xvclk".
- link-frequencies: target pixel clock frequency.
For further reading on port node refer to
Documentation/devicetree/bindings/media/video-interfaces.txt.
Example:
i2c0@1c22000 {
...
...
ov2659@30 {
compatible = "ovti,ov2659";
reg = <0x30>;
clocks = <&clk_ov2659 0>;
clock-names = "xvclk";
port {
ov2659_0: endpoint {
remote-endpoint = <&vpfe_ep>;
link-frequencies = /bits/ 64 <70000000>;
};
};
};
...
};
