Kernel-4.18.0-80.el8_nokia,smia

SMIA/SMIA++ sensor

SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension
of that. These definitions are valid for both types of sensors.

More detailed documentation can be found in
Documentation/devicetree/bindings/media/video-interfaces.txt .

Mandatory properties

  • compatible: “nokia,smia”
  • reg: I2C address (0x10, or an alternative address)
  • vana-supply: Analogue voltage supply (VANA), typically 2,8 volts (sensor
    dependent).
  • clocks: External clock to the sensor
  • clock-frequency: Frequency of the external clock to the sensor
  • link-frequencies: List of allowed data link frequencies. An array of
    64-bit elements.

Optional properties

  • nokia,nvm-size: The size of the NVM, in bytes. If the size is not given,
    the NVM contents will not be read.
  • reset-gpios: XSHUTDOWN GPIO
  • flash-leds: See ../video-interfaces.txt
  • lens-focus: See ../video-interfaces.txt

Endpoint node mandatory properties

  • clock-lanes: <0>
  • data-lanes: <1..n>
  • remote-endpoint: A phandle to the bus receiver’s endpoint node.

Example

&i2c2 {
clock-frequency = <400000>;

smiapp_1: camera@10 {
    compatible = "nokia,smia";
    reg = <0x10>;
    reset-gpios = <&gpio3 20 0>;
    vana-supply = <&vaux3>;
    clocks = <&omap3_isp 0>;
    clock-frequency = <9600000>;
    nokia,nvm-size = <512>; /* 8 * 64 */
    link-frequencies = /bits/ 64 <199200000 210000000 499200000>;
    port {
        smiapp_1_1: endpoint {
            clock-lanes = <0>;
            data-lanes = <1 2>;
            remote-endpoint = <&csi2a_ep>;
        };
    };
};
