+* Sony IMX323 DVP sensor
+
+Required Properties:
+- compatible: should be "sony,imx323"
+- clocks: reference to the 37.125M xvclk input clock.
+- clock-names: should be "xvclk".
+- dovdd-supply: Digital I/O voltage supply, 1.8 volts
+- avdd-supply: Analog voltage supply, 2.8 volts
+- dvdd-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: Low active reset gpio
+
+The device node must contain one 'port' child node for its digital output
+video port, in accordance with the video interface bindings defined in
+Documentation/devicetree/bindings/media/video-interfaces.txt.
+
+Example:
