1* Omnivision OV7740 CMOS image sensor
2
3The Omnivision OV7740 image sensor supports multiple output image
4size, such as VGA, and QVGA, CIF and any size smaller. It also
5supports the RAW RGB and YUV output formats.
6
7The common video interfaces bindings (see video-interfaces.txt) should
8be used to specify link to the image data receiver. The OV7740 device
9node should contain one 'port' child node with an 'endpoint' subnode.

11Required Properties:
12- compatible:	"ovti,ov7740".
13- reg:		I2C slave address of the sensor.
14- clocks:	Reference to the xvclk input clock.
15- clock-names:	"xvclk".
16
17Optional Properties:
18- reset-gpios: Rreference to the GPIO connected to the reset_b pin,
19  if any. Active low with pull-ip resistor.
20- powerdown-gpios: Reference to the GPIO connected to the pwdn pin,
21  if any. Active high with pull-down resistor.
22
23Endpoint node mandatory properties:
24- remote-endpoint: A phandle to the bus receiver's endpoint node.
