    +* 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 */
    + };
    + };
    + };
    +};
