+* 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.
+
+Example:
+&i2c2 {
+ ov8865: camera@36 {
+ compatible = "ovti,ov8865";
+ reg = <0x36>;
+ clocks = <&ccu CLK_CSI_MCLK>;
+ clock-names ="xclk";
+ AVDD-supply = <&reg_ov8865_avdd>;
+ DOVDD-supply = <&reg_ov8865_dovdd>;
+ VDD2-supply = <&reg_ov8865_vdd2>;
+ AFVDD-supply = <&reg_ov8865_afvdd>;
+ powerdown-gpios = <&pio 4 17 GPIO_ACTIVE_LOW>; /* PE17 */
+ reset-gpios = <&pio 4 16 GPIO_ACTIVE_LOW>; /* PE16 */
+ rotation = <180>;
+
+ port {
+ ov8865_to_mipi_csi2: endpoint {
+ remote-endpoint = <&mipi_csi2_from_ov8865>;
+ data-lanes = <1 2 3 4>;
+ clock-lanes = <0>;
+ bus-type = <4>; /* V4L2_FWNODE_BUS_TYPE_CSI2_DPHY */
+ };
+ };
+ };
+};
