    +Toshiba et8ek8 5MP sensor
    +
    +Toshiba et8ek8 5MP sensor is an image sensor found in Nokia N900 device
    +
    +More detailed documentation can be found in
    +Documentation/devicetree/bindings/media/video-interfaces.txt .
    +
    +
    +Mandatory properties
    +--------------------
    +
    +- compatible: "toshiba,et8ek8"
    +- reg: I2C address (0x3e, or an alternative address)
    +- vana-supply: Analogue voltage supply (VANA), 2.8 volts
    +- clocks: External clock to the sensor
    +- clock-frequency: Frequency of the external clock to the sensor. Camera
    + driver will set this frequency on the external clock. The clock frequency is
    + a pre-determined frequency known to be suitable to the board.
    +- reset-gpios: XSHUTDOWN GPIO. The XSHUTDOWN signal is active high. The sensor
    + is in hardware standby mode when the signal is in low state.
    +
    +
    +Endpoint node mandatory properties
    +----------------------------------
    +
    +- remote-endpoint: A phandle to the bus receiver's endpoint node.
    +
    +Endpoint node optional properties
    +----------------------------------
    +
    +- clock-lanes: <0>
    +- data-lanes: <1..n>
    +
    +Example
    +-------
    +
    +&i2c3 {
    + clock-frequency = <400000>;
    +
    + cam1: camera@3e {
    + compatible = "toshiba,et8ek8";
    + reg = <0x3e>;
    + vana-supply = <&vaux4>;
    + clocks = <&isp 0>;
    + clock-frequency = <9600000>;
    + reset-gpio = <&gpio4 6 GPIO_ACTIVE_HIGH>; /* 102 */
    + port {
    + csi_cam1: endpoint {
    + remote-endpoint = <&csi_out1>;
    + };
    + };
    + };
    +};
