+* Omnivision OV5640 MIPI CSI-2 / parallel sensor
+
+Required Properties:
+- compatible: should be "ovti,ov5640"
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+- DOVDD-supply: Digital I/O voltage supply, 1.8 volts
+- AVDD-supply: Analog voltage supply, 2.8 volts
+- DVDD-supply: Digital core voltage supply, 1.5 volts
+
+Optional Properties:
+- reset-gpios: reference to the GPIO connected to the reset pin, if any.
+ This is an active low signal to the OV5640.
+- powerdown-gpios: reference to the GPIO connected to the powerdown pin,
+ if any. This is an active high signal to the OV5640.
+- rotation: as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt,
+ valid values are 0 (sensor mounted upright) and 180 (sensor
+ mounted upside down).
+
+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.
+
+OV5640 can be connected to a MIPI CSI-2 bus or a parallel bus endpoint.
+
+Endpoint node required properties for CSI-2 connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- clock-lanes: should be set to <0> (clock lane on hardware lane 0)
+- data-lanes: should be set to <1> or <1 2> (one or two CSI-2 lanes supported)
+
+Endpoint node required properties for parallel connection are:
+- remote-endpoint: a phandle to the bus receiver's endpoint node.
+- bus-width: shall be set to <8> for 8 bits parallel bus
+ or <10> for 10 bits parallel bus
+- data-shift: shall be set to <2> for 8 bits parallel bus
+ (lines 9:2 are used) or <0> for 10 bits parallel bus
+- hsync-active: active state of the HSYNC signal, 0/1 for LOW/HIGH respectively.
+- vsync-active: active state of the VSYNC signal, 0/1 for LOW/HIGH respectively.
+- pclk-sample: sample data on rising (1) or falling (0) edge of the pixel clock
+ signal.
