Hi,

Add a documentation for the sensor ov8865 from Omnivision.

In order to ease the submission of both drivers, you should probably
split this series into two, one with the MIPI-CSI driver, and one with
the ov8865 driver.

+* Omnivision OV8865 MIPI CSI-2
+
+Required Properties:
+- compatible: should be "ovti,ov8865"
+- clocks: reference to the xclk input clock.
+- clock-names: should be "xclk".
+- DOVDD-supply: Digital I/O voltage supply, 2.8 volts
+- AVDD-supply: Analog voltage supply, 2.8 volts
+- AFVDD-supply: Analog voltage supply, 2.8 volts
+- DVDD-supply: Digital core voltage supply, 1.2 volts
+- reset-gpios: reference to the GPIO connected to the reset pin.
+	       This is an active low signal to the OV8865.
+- powerdown-gpios: reference to the GPIO connected to the powerdown pin.
+		   This is an active low signal to the OV8865.
+- rotation: as defined in
+	    Documentation/devicetree/bindings/media/video-interfaces.txt,
+	    valid values are 0 (sensor mounted upright) and 180 (sensor
+	    mounted upside down).
+- 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 <4> (four CSI-2 lanes supported).
+
+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.
Free form DT documentation is deprecated nowadays, you should be doing a
YAML schema instead (like the ov8856 driver).
